OBSERVATIONS OF COMET HALE-BOPP IN SPRINGS OF 1996 AND 1997

摘要

In the springs of 1996 and 1997, we used a new developed 1024×1024 CCD camera attached to the 1-meter telescope at Yunnan Observatory, to take photometric observations for the Comet Hale-Bopp. In addition, a 35-cm telescope, a 22-cm telescope and a common camera were also used for the observations, since this comet may become the brightest comet in our century. A lot of pictures had been obtained. They show us a "fan" and "shell" structure, also plentiful of phenomena in the plasma tail and dust tail with their variation. The positions and luminosity variations in 1996 have been measured accurately.
