The above image is a stack of three 60-second exposures obtained on 2002 January 18.37, January 18.39, and January 18.41 by the Near Earth Asteroid Tracking (NEAT) program. Discovery A series of photographs were obtained by T. Gehrels and R. Adams (Palomar Observatory, California, USA) using the 122-cm Schmidt telescope during the end of 1975 October, as part of Gehrels' survey for unusual solar system objects. As he examined these plates during the first week of November, he found a trail on an exposure obtained on October 27.15. He described the object as nearly stellar, but slightly diffuse, with a nuclear magnitude of 17. The object was subsequently found on plates exposed with the same telescope on October 28.16 and October 30.15. Historical Highlights

This image was taken on 2003 January 11.92, using a 0.25-m SCT f/5 and an SX MX516 ccd camera. The image was composed of thirty 30-second exposures. The coma was 20.6 arc seconds across, while the tail extended 22.4 arc seconds toward PA 315°. The image was originally white with black stars and the webmaster reversed this to better represent the appearance of the comet. |
