最近几天我在观测铱星的反光,感觉真不错.只是时间非常的短,从你开始感觉有东西变亮一直到看不见为止,总共才10多秒时间,可是效果还是很好的.对于铱星的观测非常适合于在大城市的星友们,因为它的亮度经常达到负等,甚至最亮-8等.有兴趣的星友可以去www.heavens-above.com上去查询一下,输入你所在的经度,纬度,高度,就可以得到一份数据,很详细的.(英文版的,作好准备)

铱星的观测

铱星系统是美国依星公司在上个世纪九十年代末陆续发射的由几十颗人造卫星组成的卫星系统。用于全球手机通信。——引自《都市星空》

呵呵,我以前也看到过一次,只是当时不懂,以为是一颗火流星罢了。

我觉的看这东西很带劲,因为经常可以看见。隔几天就会有非常亮的。我们这儿到25日晚上就有一次-8等的,爽啊!

铱星的观测

一般观测此类人造天体的时间是黄昏左右的时段,不能太晚。

铱星的观测

在日出前和日落后不久就可以观测了,但是天已变凉了,观测时要注意保暖啊!

铱星的观测

不错,不错,看来在观测铱星的同时还要把手表的精度调节好。这可来不得十几秒的误差。

用不着望远镜,比流星慢不了多少。
