Data Archive of Asteroid Observations

at MaidanakS. Takahashi and F. Yoshida(NAOJ)

Self-introduction

• Shigeru TAKAHASHI

• 高橋　茂• Nobeyama Radio Observatory

• SE (45m Radio Telescope)• Solar system minor body

(asteroids, comets, etc.)

Observations of Asteroids• Combinations of color and lightcurve

observations• Color

– BVRI– Z band is ideal, but we use I-band filter instead.

• Lightcurve– R band– Determination of Rotational Period (3-10hour)

• 5-7 nights (Sites in Japan)• 2-3 nights (Maidanak)

Observations at Maidanak

• 2003 First visit• 1.5 m Telescope

• 2006 - now• 60cm Telescope
