Images 1999-12-06 |
Analysis made on 1999-12-31 of one of the photographs taken on 1999-12-06 (see Astrophotographs (including M45, M31, M33, M42, Jupiter, Saturn) showed the presence of the asteroid (or minor planet) 29 Amphitrite (am-fi-TRY-tee, Amphitrite in Greek Mythology ). This was the first asteroid that I have ever seen. Whilst I did not set out to see or photograph it, the analysis of the photograph was made with the aim of locating any asteroids present and finding 29 Amphitrite in the picture was as thrilling as if I had seen it through the eyepiece of my telescope.

Simulated
positions of asteroid 29 Amphitrite for period 1999-11-29 to 1999-12-09 Object in photograph corresponds precisely with the calculated position of Amphitrite for 1999-12-06 21:28h UT |
Positions of 29 Amphitrite calculated using TheSky program (Software Bisque) for 1999-11-29 21:28 UT to 1999-12-09 21:28 UT, at 2 day intervals. overlaid on Photo Image. 29 Amphitrite Details (from TheSky) Magnitude : 8.9 Distance from Earth : 1.40 AU Amphitrite is about 200km wide (Physics News Update) Amphitrite was at Opposition on 1999-12-10 (IAU Page for Amphitrite) |
