| 摘 要： | 1996年7月和8月间，利用陕西天文台骊山天文观测站1．05m望远镜卡焦照相，对海尔-波普彗星进行了定位观测。该望远镜卡焦焦比为F／10，底片比例尺为20”／mm，无畸变象场约为1平方度天区．用蔡司ASCORECORDE2坐标量度促进行底片测量，归算时采用6常数模型，用PPMsouth星在做参考标准，最终给出在FK5基本系统上（J2000．0历元）各观测时刻海尔-波普彗星的α和δ观测值。

| Abstract: | The photographic observations for Hale-Bopp comet were catried out with 1. 05 meterreflector during the period of July through August, 1996. at Shaanxi Astronomical Observatory. The focal ratio of the Cassegrain system for the telescope is F/10 and the platescale is 20"/mm. The plates were measured using ASCORECORD E2 coordinates measuring instrument and reduced with the 6 constant model. The positions of reference starswere taken from PPM south catalogue. Finaly, 6 accurate positions of Hale-Bopp cometwere obtained for the epoch J2000. 0 referred to the FK5 system. |
