IMO的狮子座流星雨通报（我国有7人上榜！）
国际流星组织（IMO）的目视观测委员会的主席Rainer Arlt在北京时间昨天晚上发布了对今年的 狮子座流星雨
的初步分析，今年的狮子座流星雨的2个峰值出现在世界时17日的21:59
分，ZHR为36+-3和18日的23:05 分，ZHR为34 +-3。
IMO一共采用了来自世界各地19个国家的37位观测者的报告，其中我国
的共有7人上榜。人数名列第一！天津有2人，是我和张梦玲，北京有2人是
朱进和孟奂，还有广州的叶泉志（本论坛的小龙.哈勃),还有一位是Ming-hui Liang ,省份不知。并列第2位是美国和塞尔维亚，各有5人上榜。

Leonids 2004, update
A total of 179 visual observing periods have been collected
for the 2004 Leonid meteor shower. An updated activity pro-
file is given below. The data indicate a broad background
component with ZHRs of the order of 20-30. More data will
be necessary to decide upon the significance of the ZHRs
above 30 near Nov 17, 22h UT and Nov 18, 23h UT.

Rainer Arlt, 2004 Nov 22, 9:30 UT 不错，成绩很好 大部分是上论坛的天文同好啊。
祝贺！ 祝贺啊！！！ 好消息啊 :D :!: 祝贺祝贺 :!: :!: :!: 顶，为中国争光~~~ 祝贺,祝贺啊 ^^ 祝贺祝贺！！！ ^^ IMO于北京时间今天晚上8点30发布了狮子座流星雨的第3号通报！
我国这次有8人上榜！我第2次上榜！
天津有3人，是我和张梦玲和LAMOST，北京有2人是
朱进和孟奂，还有广州的叶泉志（本论坛的小龙.哈勃),武汉的欧阳天晶老师！还有一位是Ming-hui Liang ,省份不知。可喜的是这是本论坛的LAMOST同好的报告第一次被采用！祝贺一下！
希望大家再接再厉，在下个月的双子座流星雨的观测中能在提供报告的人数上
再创新高！！
Leonids 2004, 3rd circular
A total of 327 visual observing periods have been collected
for the 2004 Leonid meteor shower. A grand total of 1249 shower
meteors was reported. Dust trail computations gave predic-
tions for Nov 8 ~23h30 (30-rev trail), Nov 17 ~9h20 (2-rev),
Nov 19 ~6h40 (20-rev), Nov 19 ~21h40 (8-rev), Nov 21 ~8h20
(26-rev), Nov 21 ~10h (25-rev). The encounter with the 8-rev
trail was expected to show ZHRs of several 10s to perhaps
65 per hour.
Since the predicted activity levels were not much exceeding
the general background activity of the Leonid meteor shower,
it was clear that the detection of individual dust trail
natures will not be easy. As a matter of fact, the observa-
tions do not show any peaks coinciding with one of the
encounter times
The enhanced rates of November 8 are far from significant,
as they are based on very few shower meteors seen from Europe
at low radiant elevations. No reports from Asia are available
for that UT-evening.

The solar longitudes refer to equinox J2000.0, ZHRs are
computed with a population index of r=2.0 and a radiant
height correction of 1/sin(hR). nINT is the number of
observing periods in the average, nLEO the number of
Leonids involved.

？
Ming-hui Liang ？是梁明辉吧？ 有我吗？？ 这是回信：
Thank you for your Leonid observation, which I also
saw on 'meteorobs'. I have included the report in
the database.
Best wishes,
Rainer 祝贺！ 再次祝贺！ 恭喜恭喜！ 祝贺！ :o 祝贺！！ :mrgreen:
Re: ？
Ming-hui Liang ？是梁明辉吧？
请问他是哪里的爱好者？北京的吗？
我不认识。
我只是根据拼音猜测是“梁明辉”。有认识的同好能介绍一下吗？请问他是哪里的爱好者？北京的吗？ 祝贺。狮子座流星雨观测取得了好成绩，那双子座呢？拭目以待~~~~~
