STEREO Science Objectives• Understand the causes and physics of Coronal Mass Ejections

(CMEs)

• Track how CMEs move through space

• Discover the sources of dangerous solar energetic particles (SEPs)

• Map the 3D structure of the solar wind

STEREO-A/SECCHI

Space Weather Effects•Satellite Damage and Difficulties •Dangers to Astronauts •Communications Black Outs and Radio Difficulties •GPS Errors•Problems with Air Travel Near the Poles•Flow of Currents on Pipelines •Electric Power System Problems •Confused Homing Pigeons

STEREO Imagers (SECCHI)

EUVI – Extreme Ultraviolet images

Cor1 and Cor2 – Coronagraphs

Heliospheric Imagers (HI), imaging the rest of the way from the Sun to Earth orbit

August 2010 – CMEs out to Earth orbit

Media Events•Press conference: Feb. 9 at 2:00 PM US Eastern Standard Time http://www.nasa.gov/multimedia/nasatv/index.html?param=public

•Twitter session for the public: Feb. 10, 1:30 -2:30 EST hashtag #sun360

“3D Sun” on iPhone“Solaris” on Android

STEREO on a Smart Phone

What would people use/like?

Flat screen movies showing rotating sun at particular time.•Produce after press conference? •Wavebands? •Number of frames in revolution?•Movie Format (frames, mpg, etc.)?

Projected Maps – good for wrapping over spheres.SOS uses series of these to make movies. Smart phone apps use individual ones for their zoom & pan displays•Anyone else want these?
