C/LINEAR(2004 B1)between2和3 AU的日心距离观测
Observations of Comet C/LINEAR (2004B1) between2 and 3 AU heliocentric distance
摘要:
本文介绍了2006年6月21日至8月20日期间对彗星C2004B1的R波段观测结果。这些数据已被减少到表面亮度图,光变曲线,和平均径向轮廓的彗发。在两种情况下,记录了亮度的下降,持续了几天。亮度下降伴随着昏迷的形态变化。
英文摘要:
We present R-band observations of comet C2004B1 obtained in the period June, 21 - August 20, 2006. The data have been reduced to surface brightness maps, light curves, and mean radial profiles of the coma. In two cases a decrease of the brightness was recorded, which lasted for several days. The brightness decrease was accompanied by morphological changes in the coma.
