2003年11月15-16日,王宁、陆雁、高兴、李夏、段婷、尚天龙及部分其他学生前往南山天文站观测金牛、狮子流星雨。
本想观测两晚,遗憾的又是天气!!!16日中午山上竟然飘起了雪,只好作罢。总之这次和以往一样不顺利(今年就是这样!)。先是赤道仪出问题,好不容易找到原因并排除,然后电源又出问题,没带万用表和烙铁,所以只好放弃拍摄深空和彗星的计划,好在两颗彗星都看到了,恩克彗星比想象的要难以确认,凝聚度较小,大概是2-3的样子,较像M101,挺大的,没有细致测亮度,大概9等左右。林尼尔2002 T7则比较小,凝聚度至少是6,较像M76,亮度集中,估计为9-10等。
流星观测方面也不顺利,虽然对流量不抱太大期望,但月出后的两流星雨的表现也太安静了(倒是在0:00前有不小的流量——北金牛),由于在修电源所以没有记录观测。而且我在4:00以后的观测中竟然睡着了,实在是想来后悔!
另外还实验了用摄像监视头接主镜导星,还有待改进。
高兴的流星观测记录
