同好们对于明天的麒麟座流星雨有什么看法？
明天可是十年周期α-MonocerotidsActive : November 15-25;
Maximum : November 21, 15h00m UT (sol = 239.239°);
ZHR : variable, usually ~ 5, but may produce outbursts to ~ 400+;
Radiant : alpha = 117°, delta = +01°; Radiant drift: see Table 6;
V : 65 km/s
r : 2.4;
TFC : alpha = 115°, delta = +23° and alpha = 129°, delta = +20° (beta > 20° N); or
alpha = 110°, delta = -27° and alpha = 098°, delta = +06° (beta < 20° N).
Another late-year shower capable of producing surprises, the α- Monocerotids gave their most recent brief outburst in 1995 (the top EZHR, ~ 420, lasted just five minutes; the entire outburst 30 minutes). Many observers across Europe witnessed it, and we were able to completely update the known shower parameters as a result. Whether this indicates the proposed ten-year periodicity - with heightened rates in 1925, 1935, 1985 and 1995 - is real or not, only this year (or other future decadal returns) may tell, so all observers should continue to monitor this source closely.
The waning gibbous Moon on November 21 is very bad news however, as it will rise between mid to late evening across much of the world, ruining any chance of dark skies for watchers, because the radiant is well on view from either hemisphere only after about 23h local time. The expected peak time falls especially well for sites around and in the western Pacific Ocean, including eastern China, far eastern Russia, Japan, Oceania, and Alaska in North America. With the Moon so problematic, visual observing will be extremely difficult, but highly important, along with all other techniques, especially radio, which should readily detect any strong outburst from this source.
当然要看！ 2005年麒麟座α流星雨
预测极大时间：11月21日 世界时15时00分（太阳平黄经239.32°）
极大流量(ZHR)：5 有时可到400
极大中心：赤经117度 赤纬+1度
月相情况：http://ccn.lamost.org/meteor/moonphase/moon_21.gif
北纬20度（南宁、广州、海口）：全夜可观测，但下半夜有月光干扰。
北纬30度（拉萨、成都、重庆、武汉、杭州、南京、上海）：全夜可观测，但下半夜有月光干扰。
北纬40度（北京、呼和浩特、大连）：全夜可观测，但下半夜有严重月光干扰。
北纬50度（塔城、哈尔滨）：全夜都可观测，但大部分时间月光干扰严重。
IMO观测综述：年底另一个有可能带来惊喜的流星雨，麒麟座α流星雨，最近的爆发出现在1995年（最大EZHR约为420延续只有5分钟；整个爆发30分钟）。整个欧洲的很多观测者目击了它，结果我们可以以此完全更新该流星群的已知参数。无论这次爆发是否表明了该流星雨10年周期的说法，只有 今年能够证明。21日的下弦非常可恶，它将在子夜升起，赶走任何黑暗的天空。两个半球都要等到23时以后才能观测，因此最佳的地点落在西太平洋地区，包括中国东部，俄罗斯远东，日本，大洋洲和阿拉斯加。由于月光的严重干扰，目视观测将非常困难，所以其他的设备，特别是无线电，都应该用于检测来自该群的任何强爆发。
