1. Data Archive of Asteroid Observations at Maidanak S. Takahashi and F. Yoshida(NAOJ)

2. Self-introduction Shigeru TAKAHASHI 高橋 茂 Nobeyama Radio Observatory SE (45m Radio Telescope) Solar system minor body (asteroids, comets, etc.)

3. 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)

4. Observations at Maidanak 2003 First visit 1.5 m Telescope 2006 - now 60cm Telescope Obs. of Asteroids Objects 89 (Including standard stars) Nights 190 Frames 21552

5. Numbers of Nights and Objects

6. Number of Frames Subprime lending! Lehman Shock!

7. A Plan of Archive Database System How can we mange a lot of data? To assist in data processing Local use (not for open-use) Database

8. Data Archive Original Data Processed Data Query Download Results of color, rotational period, etc (832) Karin BVRI… Ephemeris Data (832) Karin Position… SQL+PHP?

9. We need the internet access !! UBAI NAOJ Korean,Russian Car Korean, Uzbek Airplane Data Server iPhone 4 made in Korea

10. Schedule Status Completion The progress will be reported at the next Maidanak meeting. Who knows? Maybe… Planning

11. Summary We have obtained more than 20000 frames from 2006. We are now planning a data archive system for asteroids obtained at the Maidanak. The progress will be reported at the next Maidanak meeting.
