Presentation Transcript

  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, butwe 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 Results of color, rotational period, etc Query (832) Karin BVRI… Download Ephemeris Data SQL+PHP? (832) Karin Position…

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

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

  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.

  12. Asteroids • Asteroids • 年齢 • Karin Family • 若い • Space Weathering

  13. Web-based search • Search keywords Query Object name, Obs. date, Frame type etc. • Thumbnails SQL+PHP? • Download links
