Visibility I / V


57752 (2002 VX8) Filmed on the first night of the November work. The asteroid at the inner edge of the main zone was discovered on November 9, 2001 by Socorro LINEAR. There will sometimes be a large (185km) 6 Hebe near the asteroid, 1906 0.047au, 2061 0.022au, photographed was 2,186au from Earth. There are those imperceptible little wanderers on stable lines who are in the thousands in the main zone. The track stays on as long as someone collides and the song disappears from tracking, for this reason e.g. these are also constantly being observed. 1Picture. first picture, measured 01: 37: 49UT 08h15m24.32s + 24d18'50.6 "20.08mag, Horizon 01:38 08h15m24.41s + 24d18'50.8" 19.97mag.
2Picture. last measurable image7, measured 1:50: 27UT 08h15m24.47s + 24d18'52.3 "20.10mag, Horizon 08h15m24.51s + 24d18'51.4" 19.97mag. Used calibration as star TYC 1928-437-1 v.11.49mag.

. It was necessary to stretch the images very strongly to bring out the measurement point. It was easy to find in the stack, though. I had to check that I had not measured the star, from the map of Alb of Simbad.
