Welcome back to PAS! It was a fun,interesting, strange weather summer, butnow it is time to get back into the swing ofthings with PAS. Over the summer, we hada great Lecture Series by Mike, a coupleattempts at & 1 successful Night Sky Train-ing Session, some wild dust storms, somerain and we are hoping that Septembercooperates with our great event line-up. Seepage 2 for the Upcoming SeptemberEvents.
At the September PAS Meeting, we aredoing Members’ Night. This is your chanceto share something astronomy related withthe Members, in a short presentation. Iwould love to have several guest speakers
for the evening, so let’s keep our presenta-tions at 30-40 minutes max. We can alsoopen this meeting up to Show & Tell. So, ifyou have something you wish to share: abook you love, a star chart, a new scope youbought, a program you enjoy... bring italong and let’s hear about it. Please sign upwith Terri so we can schedule your presen-tation into the evening. I would love to haveeveryone sign up by NOON on this day.
For this meeting, we will be havingsnacks that are provided by the members.Please bring a snack to share. A box ofcookies, a bag of chips, popcorn, anythingfinger food related, is great. Bottled waterwill be provided by President Bruce. Plates
& Napkins, if remembered, will be provid-ed by PAS, brought by Terri - someonesend me a reminder, please.
We will also have the Book Swap andMagazine Swap. Do you have older Maga-zines and Books you’d like to share? Bringthem along and at the snack table at theback of the room, put your items into thepile, and take from the pile. The idea is thatTerri does not want to take any magazinesor books home, so help yourself to the pile,and return them at a future meeting to sharewith our Members. We hope to see every-one there! ***
Members Night at PAS September 5By Terri, Event Coordinator
President Bruce Wurst opened themeeting. In attendance was: Darlene Ahl-efeld, Rick Cunningham, Don Boyd, SamInsana, Rodney Fong, Chet Schuler, AlbertTucker, Darren Johnson, Jeremy Dietrich +Mom, William & Terri Finch, Eric Stein-berg, MIke Marron, and Alex & DianeVrenios.
Vote: We started the meeting with thevoting portion. First topic was to discussthe Membership Class. We wish to add aMembership Class to the PAS MembershipForm / Dues Sheet. To do this, our Consti-tution states that we have to Vote on it. So,we discussed everything having to do withaddition of Lifetime Membership... howmuch does it cost PAS, what is the goingrate of cost per member, compared to Duescollected, and more. This discussion took at
least 45 minutes. The results of the Vote are16 Yes and 1 No. So, it was voted in to adda Lifetime Membership option on ourMembership form.
The next voting issue was about creat-ing a Paypal account for the purpose of easeof anyone who doesn’t want to pay with acheck, or pay cash to Mike at an event. So,we voted on adding Paypal. What thiswould consist of is, we make a Paypalaccount, and then we get electronic accessto the Checking Account PAS has, andTerri would be in charge of transferringmonies from Paypal to the Checking ac-count as monies come in. Paypal doesn’tcharge any fees to Non Profit organiza-tions, so there would be no cost to PAS tohave this account. The way Paypal works isthat anyone can donate or pay for their
membership through Paypal, into the PASPaypal account, and when they do, Terriwould receive an email stating that monieswere added to the Paypal account. Then,sometime soon after they are deposited andable to be moved around, she can then sendthe monies, electronically to the PASChecking Account. It would just make iteasier on some of our new members, andsome existing members, who prefer to paywith Paypal. The voting results were 16Yes and 1 No. Paypal will be added as anoption to join or donate to PAS.
Then we talked about the Pizza Party.The purpose of the discussion was to getagreement with everyone that we move thePAS End of the Year Pizza Party to theApril Meeting of the Minds, make it aclosed meeting, also have the Awards Cer-

September PAS EventsBy Terri, Event Coordinator
At the Meeting of the Minds, we havebeen having a really great collection ofmini presentations by PAS Members. Ifyou would like to join in the fun, think upsomething you wish to present on, havingto do with anything Astronomy related, andlet me know the title of your presentationand the length. I will schedule you into theMeeting of the Minds or into the September
PAS Meeting, depending on which is com-ing up next, so that we can hear all aboutyour favorite topic. Past Presentations byEric Steinberg, Alex Vrenios, Darlene Ahl-efeld, Chris Johnson, Sam Insana, and otherPAS members, has really made the Meetingof the Minds a meeting that has worth toour club members. We have to meet once inawhile for voting, discussion, etc... oh, and
to party, but to have a special presentationis really worth it. I totally appreciate allwho have done mini presentations and allof those presenters to follow. Thank you somuch and let’s keep our meetings interest-ing to everyone! Sign up today!
Meeting of the Minds PresentationsBy Terri, Event Coordinator
3PAStimesSeptember 2013
In attendance was: Earl DeLong, DonBoyd, Terry Dancer & his Dad, Terri &William Finch, Albert Tucker, Rick Cun-ningham, Sam Insana, Kraig Nelson, Dar-lene Ahlefeld, Eric, Ora & Noah Steinberg,and of course, the Host of the party, MikeMarron. We also had a guest: Tom Hines.
The potluck started about 5pm. Wil-liam and I arrived about 4:50pm with pizzafrom Domino’s. The winds were wild. Itwas forecast that by 7pm, the winds woulddie down, but we left at 1am, and the windsnever gave up. However, Eric, Terry and 2other scopes set up. Since the other twoscopes were smaller than 8”, they weresoon put away due to the high winds. Asdark took over, we gathered outdoors in theobserving area and had a super, wonderful,informative, entertaining presentation byEric. Thank you so much Eric. Sam wasgoing to talk about setting circles, but Ericcovered that. And I was going to take ev-eryone on a tour of the night sky, constella-tions and lore, but Eric covered that as well.
It was really an awesome presentation andI found out later that many of the attendeesappreciated it, as they didn’t know thatinfo. So, Eric really gave us all a greatpresentation.
After the presentation, Eric showed afew more objects in his scope, and Terrysearched for and found the Crab Nebula.There were holes in the clouds, so we couldsee a few objects, but the cloud cover wasat least 80% of the sky, most of the night.And the winds just kept blowing and blow-ing.
I wish to thank everyone who broughtfood to share. Pizza was brought by theFinches. Sam brought coleslaw and WhiteCastle burgers, which was a nice, differenttreat. Darlene brought puffs and grapes.There were chips and cheese sticks, andchicken wings and 2 buckets of KFC. Plen-ty to eat. About an hour after Eric did hispresentation, and a few of us got tired offighting the wind, the party broke up. Ericleft, Sam left, and the scopes were put
away. Those of us who came and didn’ttake out our scopes were disappointed inthe weather. And due to the cloud cover, nored flashlights were needed to see your wayaround, as there was plenty of glow fromthe light pollution.
It was a good event, however, it wasn’twhat I had in mind. So, we will try thisagain at the next event. Hoping for clearskies, good temperatures, NO wind if at allpossible, and we hope to see you there. Ifyou didn’t attend, you only missed Eric’sgreat presentation. We can have him repeatit at a later event. It was well worth a repeatperformance! Thank you again, Eric!
Kraig Nelson writes: this was my firstevent at Mike's. What a terrific experience,clouds notwithstanding! I learned a greatdeal from the well-informed speaker andenjoyed the ensuing interaction with clubmembers. I look forward to the next eventat Mike's historic venue. Let's hope forclear viewing.§
1st Night Sky Training Session (NSTS) at Mike’s Apr 13By Terri, Event Coordinator
In attendance was: Terri Finch with an8” scope, William Finch with a 10” Scope,Don Boyd with his 6” scope, Earl DeLongwith his 10” scope, Sam Insana with his 8”Scope, & Darren Johnson with his 10”scope. Our contact, Julie, was a very goodhostess. She provided us with plenty ofpizza and drinks. We arrived at 6pm for set,and within minutes of arriving, the pizzaarrived. So, while setting up, we also en-joyed food. 7pm came and so did thecrowd. I would estimate attendance 25adults & 75 kids. Once the crowd came,there were no more breaks, as it was aconstant flow of people through our scopes.Most of the scopes shared Jupiter for thelongest time. I took Sirius, at first, to try toalign my scope. I was stuck on Sirius forabout 30 minutes and then the Orion Nebu-la, not super visible naked eye, but enoughI could find it, was above the building, so Itook Orion for about another 40 minutesbefore the bush by the building, and thebuilding hid Orion from view. Then Imoved to Arcturas, also with the plan toalign my scope, and got stuck there foranother 40 minutes talking about Arcturas
and showing it. The crowd slowed down abit and I moved my scope to align it on theNorth Star. Then i was stuck there for an-other amount of time, right up until wewere told to pack up for the evening. Iheard about Jupiter and Saturn, but neversaw them this night. However, I did giveout about 35 Q & A Prizes through thenight. Totally enjoyable event. One thing Ilove about doing this school’s star party isthat the attendees are very interested inwhat we have to show them, and they askquestions, participate in conversations, andeven if they don’t know what we are talkingabout, they try to learn more. It is really apleasure to do this event. We are planninganother event at this school in Fall 2013.Watch for the announcement. They haven’tdone any Fall events, so I suggested achange in the sky would be a good thing.
Weather wise, the thin cloud cover waslike having a bunch of light pollution. Mostof the scopes stayed on bright objects be-cause of the amount of reflected light com-ing from the clouds. We hope for clearskies at the next week. Many thanks to Juliefor having us at her school!
Earl writes: We had another well at-tended star party at Benchmark school.Don, Terri, William, Sam, Darren and I allarrived at 5:30PM. We moved to the bas-ketball court and set up our equipment.While eating our pizza, we were a littleconcerned about the wispy clouds to thewest. As the sun set, these dissipated. Thecrowd started to arrive right at sunset andwe frantically searched the western sky forJupiter. I was the first to spot it and we allturned our equipment on it. As the eveningprogressed, I turned to Saturn. I used ayellow filter on this object for the first timeand was impressed with how it helped theimage. Everyone who stopped by re-marked on how much clearer the view wasthrough my scope. Once the crowdsthinned, I quickly star aligned and viewedM44 the beehive cluster, Izar a double starin Bootes (I was unable to resolve it at100X), and Bootes 39 a nice double star ofequal brightness. Please consider joiningus at the next public event. It is always anenjoyable time.

CTCA/PAS Solar Viewing & SkyTourEvent Thursday April 25th, 2013 Report byJoseph T Collins, CancerFighter @ CTCAWRMC & PAS Member PAS Attendees:Don Boyd, Joe & Renee Collins and StevePalmer. We had a combined total of twen-ty-five ‘customers’: CTCA patients, care-givers, and family members join us up onthe 5th floor garden terrace, eleven for solarviewing, and fourteen later for the SkyTourevent. This was the highest turn-out tomemory, and the first time we have had thisevent on a Thursday. CTCA well publi-cized the event, plus there was a lot ofanticipation for us to come out since we hadto reschedule our last two dates in April dueto cloudiness. The skies for this event wereclear of clouds, but we had high altitudeturbulence visible when looking at the limbof the Moon and haziness from the horizonto 20˚altitude due to dirt kicked up by thewind mixed with a little smog. Visibilityconditions did not hamper viewing of Jupi-ter, Saturn and the Moon for our customers.We started the SkyTour event right on timeat 8pm, but missed the overhead flight ofthe ISS while we were doing our star align-ments! We chose to run the event until11:30pm to view the tail end of the Lyridmeteor shower: a few folks spotted shoot-
ing stars.Joe Collins [email protected]: Solar
viewing: Folks looked in Don’s scope tosee the sunspots on the full solar disc atabout 30X magnification, and then wouldcome over to my scope to view the filamen-tary structure of the sunspots umbrae athigher magnification ~75X. The total sun-spot count for today was 95, but of thosefacing us, we could only see the 15 or solargest of these. There were two activegroups of sunspots we focused on: AR1723and AR1726. Spaceweather.com reportedtwo coronal holes and probability of anM-class flare of 40% over the next twodays. Two small ‘weird-looking’ sunspotswere observed near the reported locationsof the coronal holes. I confirmed my solaralignment method (again) on my CelestronC-11 SCT telescope obviating need for asun-spotter/viewfinder. I will documentthis for PAS…very quick method for SCTtelescopes with computer-controlledmounts!
During the SkyTour, I showed custom-ers sector G-3 of lunar surface around thecrater Tycho, easily identifiable due to itsmassive ray system. For armchair astrono-my, I recommend the Moon Atlas athttp://www.lunasociety.org/atlas/. The full
moon’s illumination was so intense that forsafety’s sake, I pulled a ‘Corey Hart’, andwore my sunglasses at night. For custom-ers, I used two sets of filter glasses. Ironi-cally, I received my 2” 13%T lunar filterthrough the mail from Orion the day afterthe event, so I won’t have lunar filter issuesfor future Moon viewing events. Weviewed Jupiter and its moons, Saturn and itsmoons, Polaris, Cor Caroli, Tegman, Sirius,Castor, M42 Orion Nebula/ Trapezium, M3globular cluster, and the Stargate clusterasterism. I shared the new Sky & TelescopeJupiterMoons and SaturnMoons iPad Appswith customers and showed one patientinterested in Astronomy how to access col-lege-level Astronomy courses via iTunesU. The full ‘Pink’ Moon’s brightness pre-vented us from viewing many deep spaceobjects (M42 and M3/M5 were mostlywashed out by moonlight glare) but it wasa good night for viewing binary stars andSaturn being almost at opposition lookedspectacular! To improve the viewing ofSaturn, I used a grey neutral 1.25” filterfrom Albert Tucker with my TeleVue18mm eyepiece. This filter suppresses straylight from the Moon andfluctuations/refractions off of the atmo-sphere; without it focusing on Saturn was
CTCA Apr 25By Joe Collins
Many thanks to Mike Marron for host-ing this party. In attendance was TerryDancer with his 8” scope, William & TerriFinch with a 10” and 8”, Rick Cunninghamwith a borrowed scope of about 4”, Albertwho came with binoculars to watch themeteor shower and about 5 people from thepublic. The potluck started at 5:30. Williamand I arrived about 5:15pm. It was a greatday for an event. After dinner, we set up ourscopes. The public started showing upabout 7:30. The public didn’t leave until12:30am. The plan, originally for thisevent, was to have the public star party andthen with the time that was left, do a privatesession, maybe even some NSTS. But, withthe public sticking around, we decided toshow more objects. Many thanks to Terrywho kept the public busy. Don and Iworked in the Asterism list. We viewed theasterism and using the annoyingly brightMoon of the evening, we judged if theasterism would be bright enough in a
school star party setting. Then we made alist of the asterisms that we thought we’dlike to try at the next school. Here’s the listwe came up with: Asterisms with names ofIC37, Sailboat and Stargate. The rest of theasterisms we viewed seemed too faint touse for a public event. We will continue tocheck the asterism list, as we only made asmall dent in it. While Don was looking forAsterisms, William was playing aroundwith filters and eyepieces on Saturn. And Iwas trying to find out how well my Go-toSystem was working, so I did an alighment,and then put the scope on the Orion Nebula,and then walked away to Terry’s or Don’sscope to view with the public, and when Icame back about 10 to 15 minutes later,Orion was still in the view finder. So, then,I did a go-to to Saturn and the go-to foundSaturn. I’m still not skilled at using myGo-to, but I am glad I have it. I just need toget out and practice using it more, to getmore familiar with it. About 11:30, the sky
got a bit mushy. We looked for objects andmost of the scopes packed up and called ita night. Don, Willam, Rick and I kept ourscopes up and tried to work our way aroundthe horizon mush. 12:30 came and the pub-lic was leaving. It was 2am before we left,after packing up, then visiting for a bit withKevin Harcey & Bob Senzer. Mike hadpassed out in bed right after the public left.It was a very good event. The event detailschanged from the original plan but I thinkit went very well. Thanks to all who attend-ed and showed the public the awesomenessof Astronomy! I’d like to note one thing,who ever picked a waxing Gibbous moonfor Astronomy Day, was not someone whowas going to be outdoors viewing with ascope. The moon was too large and in theway and really made it difficult to have asuccessful viewing session for anythingfainter than the Orion Nebula.

emony that same day. The Pizza would bepaid for by PAS, and not charged to thePAS members, however, putting cash in thesnack fund would help pay for the pizza,but would not be a request or requirement.This was agreed upon, even after talkingabout the status of PAS’s budget and howeach person on the PAS Roster in 2012 costPAS $25.13. Then Darren came up with theidea of having the pizza party donated, sohe is going to research that situation forPAS and get back to Terri on it.
We also discussed taking in advertisersto help defray the cost of some things PASpays for. We hope to implement that soon.
The third topic discussed was the sta-tus of the PAS Telescopes for borrowing
within the club. The question was, shouldwe repair the 12” scope for $1400 to$1600? The overall consensus was that weshould hold off on repairs to the 12”, fix upand get ready the 8” and 10” for lending outto PAS Members, and see how it goes withthose two scopes for a year or 2. Then, if wehave enough borrowing of PAS telescopesby club members, we can consider repair-ing the 12” scope at that time. So, Bruceand Terri will get the scopes ready forlending, with a sign out sheet of all itemsincluded in the borrowing of the scope, andstart the process soon. A list of what scopesare available and accessories will be onlinesoon.
We then turned the presentation time
over to Alex who did a fine presentation onStar Charts, Laser Pointers, Red Flash-lights, and Stellarium. When Alex complet-ed his presentation, we had Darlene set upStarry Night. Her computer wasn’t cooper-ating so when she got to an auto part, we lether run that in the background while Ericdid a presentation with his favorite StarCharts & Sky Safari for Ipad. Then Sam didhis star charts and to close out the evening,Terri covered her star charts. It was anawesome night! If you missed this meeting,you missed some great Star Chart info. Iwish to thank all who sent in a proxy oremail vote, as their votes were added to thecount. See you at the next Meeting of theMinds.§
more difficult.Don Boyd [email protected]: I
showed the sun, moon, Jupiter, Saturn, Cas-tor, beehive cluster, M42 and the asterisms:“IC”37 and the Stargate. I tried some otherDSO’s, the open and globular clusters weretoo faint tonight due to the full moon.
Acknowledgements- Thanks goes toJennifer Kehren who provided plenty ofcopies of our handouts, meal tickets and‘catchy’ signage advertising the event.Thanks also go to PAS member, StevePalmer who visited us around 10pm andstayed to help us with breakdown and pack-ing up at the close of the event.
Next time- We (PAS AZ) are lookingforward to coming out again next month onTuesday May 7th.

Meeting of the Minds June 27
PAStimes September 20136
It was a lovely day for a TelescopeWorkshop. The parking lot of Bookmanswasn’t as busy as normal, probably due tothe holiday - Cinco De Mayo. We had 2public RSVP’s, of which one showed up &an extra attended. Allisha Collinson attend-ed to find out what telescope to purchase.Prior to Allisha showing up, Rodney Fang(who had attended the PAS meeting onMay 2) was there with the same questions.So, we did a double “What telescope shouldyou purchase?” Q & A session.
I wish to thank the Telescope Teachersfrom this event: Earl DeLong, WilliamFinch, & Don Boyd. I’d also like to thank
Bookmans for providing the space to havethis event. They put us in a new area. Weare now at the front of the store, on the rightas you walk in, in a little sit down, cafelooking area. The magazine racks that werethere, have been moved to other locationswithin the store. And I heard they are mov-ing around and expanding their musicalinstrument section, thus the reason to haveus move to a new location within the store.So, we are right there, in the front, as youwalk into the store. Look along the backwall to the right of the Trade In counter. Itwas a very successful event.
We had 2 visitors while doing the
event. Jim Bensfield (a PAS Member whojoined just over a year ago) stopped by withhis grand daughter to pick up his Year inSpace Calendar from me and talk abouthow is granddaughter was very interestedin astronomy. And we also had a surprisevisit from one of my music students, JenPerreault & her daughter, Maci. It was avery enjoyable afternoon. The sky wasovercast most of the event (as now we areright by the front window - I can see out-side) and the winds picked up quite a bitfrom the start of the event to the end. Welook forward to the next Telescope Work-shop at Bookmans. See you there!§
Bookmans Telescope Workshop May 5By Terri, Event Coordinator
CTCA/PAS Solar Viewing & SkyTourEvent Tuesday May 7th, 2013 Report byJoseph T Collins, CancerFighter @ CTCAWRMC & PAS Member
PAS Attendees: Joe & Renee Collins.We had a combined total of eighteen ‘cus-tomers’: CTCA patients, care-givers, andfamily members join us up on the 5th floorgarden terrace, two for solar viewing, andsixteen later for the SkyTour event. Therewere several CTCA patient events prior tothe SkyTour so the solar viewing was lessattended than last time, and we nearly can-celled due to high wind gusts. Fortunately,the wind settled for the SkyTour portion ofour event. Due to superb publicity at theCTCA patient events, we actually had moreattendees than last month for the SkyTourportion of the event which was a pleasantsurprise. The evening was comfortably coolfor some folks, but the wind chill madesweaters a good idea. There were cloudshugging the mountains and peripheral hori-zon, but 90% of the sky was crystal clearfor stargazing.
It is notable and ironic that sometimesthe nights forecast to the worst, turn out tobe the best! I was already struggling withthe call to cancel/reschedule this event be-cause of the cloudiness/wind weather fore-casts, but despite the wind, the stargazingcomponent of the SkyTour was 'excellent'as predicted by Accuweather. I decided torun the event because the back-up date 7/21was only forecast to be 'good' for stargazingwith 48% cloud cover predicted.
Solar viewing: I weathered 25-30mph
gusts on the 5th floor garden terrace duringsolar viewing. My scope was rigid againstthe wind with no bothersome vibration dueto the wind apparent with a 32mm eyepiecebut it was noticeable at night for my 13mmeyepiece. I am sure the wind gusts wouldhave been problematic for our memberswith large tube reflector and refractor tele-scopes. It was somewhat comical- my foldup chairs flew across the terrace, my drinksflew to the ground from the tables creatingspills to clean up. I hunkered down andcreated 'wind blocks' out of available ta-bles- that extra setup-up and ‘pause time’during the worse gusts cut the solar viewingtime by an hour (did solar viewing from6:15pm until sunset). Still, I had decentviewing of AR1739 sunspots with two cus-tomers [In retrospect, I should have justcancelled the solar viewing component].Fortunately, the wind died down about anhour after sunset, so Renee and I continuedwith the SkyTour event.
During the SkyTour: I showed sixteencustomers Jupiter and its moons, Venus,Saturn and its moons, and M3, M5, M13,M53 globular clusters. M13 just happenedto be in the darkest part of the sky andlooked awesome! Saturn and its ring was acrowd pleaser! Even with clear skies, it wasdifficult to see more than a hazy spot or‘smudge’ of M82 and M101. We stargazed: Arcturus, Spica, Sirius, and manymultiple star systems: iota Cancri, Algieba,Castor, 54-Leo, Cor Caroli, Algorab, 35-Com, 24-com, 19-Lyncis, Porrima, andAlbereo. Faint, but tantalizingly visiblewith 13mm TeleVue eyepiece, we were
able to see M57 ring nebula and the ‘ghostof Jupiter’ and ended looking at the Star-gate cluster asterism. We ran the event from8pm until 12:30am 5/8. We were ready tobreakdown at 11:30pm, but we had a lastminute customer, a caregiver of one of theemployees at CTCA undergoing surgery.Since we personally knew both of them,and she told us she would likely not be ableto join us in the future, we did a specialSkyTour for her for another hour. She re-vealed to us afterwards that she is seriouslyconsidering getting a degree in Astronomy!

Here in our own galactic backyard, theMilky Way contains some 200-400 billionstars, and that's not even the biggest gal-axy in our own local group. Andromeda(M31) is even bigger and more massivethan we are, made up of around a trillionstars! When you throw in the TriangulumGalaxy (M33), the Large and Small Ma-gellanic Clouds, and the dozens of dwarfgalaxies and hundreds of globular clustersgravitationally bound to us and our nearestneighbors, our local group sure does seemimpressive.Yet that's just chicken feed compared tothe largest structures in the universe. Giantclusters and superclusters of galaxies, con-taining thousands of times the mass of ourentire local group, can be found omnidi-rectionally with telescope surveys. Perhapsthe two most famous examples are thenearby Virgo Cluster and the somewhatmore distant Coma Supercluster, the lattercontaining more than 3,000 galaxies.There are millions of giant clusters likethis in our observable universe, and thegravitational forces at play are absolutely
tremendous: there are literally quadrillionsof times the mass of our Sun in these sys-tems.The largest superclusters line up along fil-aments, forming a great cosmic web ofstructure with huge intergalactic voids inbetween the galaxy-rich regions. Thesegalaxy filaments span anywhere from hun-dreds of millions of light-years all the wayup to more than a billion light years inlength. The CfA2 Great Wall, the SloanGreat Wall, and most recently, the Huge-LQG (Large Quasar Group) are the largestknown ones, with the Huge-LQG -- agroup of at least 73 quasars – apparentlystretching nearly 4 billion light years in itslongest direction: more than 5% of the ob-servable universe! With more mass than amillion Milky Way galaxies in there, thisstructure is a puzzle for cosmology.You see, with the normal matter, dark mat-ter, and dark energy in our universe,there's an upper limit to the size of gravita-tionally bound filaments that should form.The Huge-LQG, if real, is more than dou-ble the size of that largest predicted struc-
ture, and this could cast doubts on the coreprinciple of cosmology: that on the largestscales, the universe is roughly uniform ev-erywhere. But this might not pose a prob-lem at all, thanks to an unlikely culprit:dark energy. Just as the local group ispart of the Virgo Supercluster but recedesfrom it, and the Leo Cluster -- a largemember of the Coma Supercluster -- isaccelerating away from Coma, it's con-ceivable that the Huge-LQG isn't a single,bound structure at all, but will eventuallybe driven apart by dark energy. Eitherway, we're just a tiny drop in the vast cos-mic ocean, on the outskirts of its rich, yetbarely fathomable depths.Learn about the many ways in whichNASA strives to uncover the mysteries ofthe universe:http://science.nasa.gov/astrophysics/.

It was a good star party. I got there at5:30 and Mike was already there eatingpizza, Albert arrived a few minutes laterand Leah arrived before 6. There was noth-ing to see until 6:30, when I saw Jupiter,because the moon did not rise until 8:30. Itwas almost 7 before we could see anythingexcept Jupiter. I did an alignment on my 6"goto reflector, and showed the DoubleCluster and ET Cluster. The participantswere well behaved and orderly, and wewere well taken care of. There was plentyof pizza, and one of the teachers delivered
water to everybody.Leah adds: "The star party went very
well! It was a little cool towards the end,but the sky was beautiful and clear. I ar-rived around 5:50, and Don, Albert andMike were already there. Since the Sundidn't set till 6:30, I brought a solar filterand my solar system scale model. The solarfilter didn't do much good because the Sunwas behind a tree. However, I was able toshow some of the kids my solar systemmodel while waiting for the sky to get dark,and Mike showed them his meteors of
course. As soon as it was dark enough, Ishowed Jupiter and its moons in my scope(6" newtonian dob). All four moons werevisible - two on each side. I stayed onJupiter all night because nobody said thatthey had already seen it. I understand thatby the time I was able to show Jupiter, Donhad already switched to star clusters. Onoccasion, when people asked, I also an-swered other questions such as what con-stellations we can see in the sky. A good(and educational) time was had by all." ***
Star Party at Canyon Springs School in Anthem, Feb 27by Don Boyd
Many, many thanks to everyone whodonated plastic grocery bags to this event!We probably used about 200 of them. Whatwe discovered is that Rancho Gabriela gotwise this year and provided the students ofK - 6 with Walmart plastic bags. In themorning, though, we saw grades 7 and 8first, and so they got our plastic bagspacked with goodies. Now I have severalplastic trash bags of bags left for anotherevent.
Many thanks to my Rancho GabrielaTeam. From PAS we had in attendance:William Finch who assisted in the givingaway of stuffed bags, Terri Finch who didQ & A with the students who would stopand talk for a moment. Don Boyd who didSolar viewing, Earl DeLong who assistedwith bag stuffing, bag give away and crowdcontrol (a very needed position), JerryBelcher and his friend Scott, who did Solarviewing, Matt Kohl who did bag stuffing,passport stamping, and bag handout andDarren Johnson, who did Solar Viewingwith us, and Chris Johnson who alsobrought his solar scope.
The day began very hectic while wegot set up, not under the gazebo from lastyear, but along the side of the Gym forwhich the shade wasn’t too bad. We hadshade all day, as the Sun crept across the
sky. It was cooler in the morning hours, butsoon got up to 85, which was nice com-pared to previous years that seemed like1,000 degrees. Jerry and Scott hid under anumbrella most of the day. Breakfast wastasty, although not very diabetic friendly.Lunch was subs, chips, and there was plen-ty to eat and drink.
We first saw the 8th Graders. It seemedlike they weren’t that interested in viewingthrough the scopes. But the 7th Graderswere awesome! They spent a lot of timetalking and asking questions. Then the 6thgraders were ok, followed by the 3rd and4th graders. I expected 4th grade to be moreinterested in space, as that is when I becameinterested and was taught it in school, but3rd and 4th graders all said they hadn’t hadanything on the Solar System, yet. Then wehad lunch. Then we saw the 5th graders,Kindergarteners, 1st Grade and lastly 2ndgrade. The 1st & 2nd Graders were veryintriguing and questioning. The whole daywas exhausting but fun, interesting and agood time.
I wish to thank Natalie Sawyer forinviting us this year. Previous years we hada different contact at the school, who wasjust as awesome as Natalie. This schooltakes good care of us, checking to makesure we got fed, letting us know the sched-
ule, and just being a great host to the event.If / when we do this event again next
year, I would like the same location butMatt made a suggestion. He said we shouldset up the handout table indoors, and justhave the solar scopes outdoors, and I got tothinking, maybe have the kids pick upsomething from the scopes, a handout orsomething, as they make their way throughour display. The other thought that some-one suggested was to make a handout aboutwhat kind of careers can be obtained inAstronomy. Since we are a club, when thekids ask us about our jobs, we have beendistinguishing between our day job andPAS as a hobby. I realize this doesn’t fitCareer day the way the teachers want it to,but maybe next year we can make a careerhandout with ideas of the kind of jobs onecan find in an astronomy field. We will dosome research on this and create the flierfor next year.
Many thanks to everyone who attend-ed, helped, and was there to support thisevent.

Rancho Gabriela May 7By Terri, Event Coordinator for PAS
Two years ago, a team using the Hubble telescope spotted a fourth moon orbiting Pluto, and a year later, they discovered a fifth.Since then, they've had the boring names of P4 and P5. No more. The International Astronomical Union officially christened the moonswith appropriately awesome names. Kerberos is named after a three-headed dog that guards the gates of hell, and Styx is named after theriver separating the living from the dead. The names were the second- and third-place winners in an international public vote. "Vulcan"actually won, but the IAU vetoed it because it wasn't associated with Pluto in mythology. Besides, we need that one for when we meet thereal Vulcans! ***

PAS Name Badge Order Being PlacedBy Terri, Event Coordinator
PAS memberships last from January toDecember. We start collecting the member-ship renewals in September for the follow-ing year to make it easier on Mike, ourTreasurer, to update the PAS Roster. Thedeadline to pay your 2014 dues is January31. If your dues are not received by then,you will be removed from the PAS Roster,the PAS Website (as a PAS Member mean-ing you have no access to the Private infoon the site) and the PAS email list. This isa lot of work for me. I prefer to leave youon the lists. So, I’m asking that everyonewho plans to be a 2014 PAS Member,
please, get your dues into Mike prior to theend of Jan. 2014, so that I do not have toremove you from the various locations &then add you again when you do catch upon your dues. This past year we let quite afew members slide.... some hadn’t paiduntil June 2013, for their 2013 dues. Please,do not do that this time. I will remove youJan 31. We hope you stay with PAS for avery long time. Put your membership duesin the mail today, or bring them to the nextevent that either Mike or Terri attends (tosave postage).
Be sure to use the 2014 membershipform, found on line at this link:http://www.pasaz.org/forums/downloads.php?do=file&id=18. In January 2014, I willsend out emails to those who have notrenewed. If you are unsure if you need torenew, you can check the PAS Roster atthis link (Members only)http://www.pasaz.org/forums/downloads.php?do=file&id=48 The Roster should showthat you are current for 2014. If it shows ayear prior to 2014, you are due to pay yourdues. ***

My first set of star charts was a col-lection of 16 maps spread throughout anastronomy book. The book covered every-thing one needed to know about the con-stellations, stellar objects, telescopes,eyepieces, etc. It was a terrific introductionto the hobby, but it wouldn’t stay open onany one page long enough to be of muchhelp under the sky.
My next set of charts was a boundversion of the Wil Tirion Sky Atlas2000.0, an excellent reference that was amajor expense for me at the time. Translat-ing a night’s observing plan into a set ofcharts, then flipping back and forththrough the pages got old fast. I bought thesame set of charts on heavy loose-leaf pag-es printed with white stars on a black skybackground. This was another luxury pur-chase but it greatly simplified my observ-ing sessions. Imagine my delight to see aWil Tirion star chart app for my iPhone!
If you are familiar with either thebound or the loose-leaf versions of WilTirion’s star charts, you already know theyare of very high quality and are intendedfor the serious observer. The Star Chartsby Wil Tirion iPhone app contains 18maps, each representing a section of thesky. There are 2 polar maps and 16 sec-tionals, 8 above and 8 below the celestialequator. Each of these maps is about 70degrees tall and 50 degrees, or 3 hours ofRA, wide. (There is some overlap betweenmap sections.) It’s a very professionallooking presentation.
When you first start the app, it selectsthe map that corresponds to what youmight see in the sky from your current lo-cation on Earth. Once active you canchoose any of the 18 maps manually. Youcan also select a map by constellationname or by star name. (This option justbrings up the map that the constellation orstar is on. It does not bring that object tocenter, as some reviewers would like it to.)Once a map is displayed you can swipe thescreen left or right to switch to the nextmap east or west of the map you’re on, oryou can swipe it up or down to get to thecorresponding northern or southern sky’spolar map. When you get to the mapyou’re interested in, you can use pinch andzoom gestures to adjust the level of magni-fication. The map number is displayed atthe top of the screen. Four buttons acrossthe bottom are labeled Layers, Legend,Settings (gears icon) and Help (questionmark).
The Layers screen lets you turn ongrid lines, coordinates, constellationboundaries, object names, and the namesof stars and galaxies. The Legend screenshows you the star size vs. magnitude, asdisplayed on a map at maximum zoom. Itshows the symbols used for the variousdeep sky objects, like stars, clusters andnebulae, and defines the codes that indi-cate their source (Messier, NGC, etc.). Iteven includes a complete listing of theGreek alphabet!
The Settings screen lets you choose
between auto-map-select at startup ormanual, south- or north-up views, black orwhite background, and a red filter to pre-serve night vision. That’s the positive partof this review; now for the negative.
First and foremost, star charts are notwell suited to being viewed on a tinyscreen. That said, each time a new map isselected it takes a second or two to dis-play. It presents one rectangular tile at atime, as if each map is being generated fordisplay every time it’s needed. (Not know-ing how this software works, I hesitate tocomplain about that, but it seems to methere ought to be a way to flash a completemap onto the screen all at once. This maybe a non-issue on an iPhone 5, e.g., or anysmartphone with a faster processor, morememory, etc.) Finally, you discover thatthe charts only go down to the 6th magni-tude and even at maximum magnificationonly the brightest stars are labeled, limita-tions I found to be very disappointing.
The overall system design of this appis classy looking, very professional andsupportive of a $3.99 price tag. When youstart the app in the field, however, you re-alize that it’s distractingly slow and hardto read. Then you think that maybe itwould be better on a newer, faster iPhone,or better yet an iPad. But while mag 6 starcharts are a good choice for beginners,they just don’t go deep enough for the in-termediate or more advanced observer.***
A Review of “Star Charts by Wil Tirion” App for Apple iPhoneBy Alex Vrenios, PhD, July 2013
Website: http://observethemoonnight.orgNASA’s next mission to the Moon is launching in September. The Lunar Atmosphere and Dust Environment Explorer (LADEE) is
scheduled to launch from the NASA Wallops Flight Facility on 6 September 2013 at approximately 11:27 PM US Eastern Time. LADEEwill orbit the Moon collecting data on the Moon’s thin exosphere and the lunar dust environment. For more information about LADEE,please visit http://www.nasa.gov/mission_pages/LADEE/main/index.html.
