提醒下,在没有月亮的天空,我们大约能够看到20颗流星雨每小时。
The Orionid meteor shower will probably rain down the most meteors before dawn on Wednesday, October 21, 2009.猎户座流星雨大概在2009年10月21日星期三黎明之前降下最多。
The best time to look for these fast-streaking Orionid meteors is between midnight (1 a. m. daylight savings time) and dawn for the next few mornings.寻找这些快速划过的猎户座流星雨的最佳时间是从午夜(夏时制凌晨1点)到第二天一早的黎明前。
This is the annual Orionid meteor shower.这就是每年的猎户座流星雨.
