[观测日记]双子座流星雨：还是失望
12月9日，天气晴朗。做完作业，我从22：00开始观测。极限星等很差，只有2.5-3.0等。观测了1小时，只有22：24观测到一颗2等的。虽然不亮，还是让我兴奋了一会儿。第二天早晨起来，看到金星在高空闪着光芒。觉得很有趣，在那里看了2分钟，竟然碰到了一颗-4等的火流星！就是从金星附近滑过。我一看：6：43。
11日，阴天下雨。12日天又放晴了。12日22：00开始，22：34看到一颗0等的，棒！22：53，我正心不在焉的想去年流星雨的事情，看到流星后几秒钟才反应出来：2等一个！
13日，也就是今天早晨。4：40摸黑起床，好冷啊，大约只有7、8度。不过我还是开始观测。天气不错，可以看到4等星。进行了50分钟的观测，结果就是一颗双子座流星也没看到，只看到了3颗偶发小流星，让我大失所望。
今天和明天我还将进行观测。
我给IMO发去的报告。
Mr.Arlt, I observated Geminids on Dec.9th,10th and 12th, and observated 4 GEMs and 3 SPO. There're only three GEMs in the form below. Because one was observated by accident. The morning on Dec.10th(E8Time), I got up and watch the Venus. Suddenly, a fireball mg. -4 fell down near the Venus, the time was 6:43E8T(22:43UT), the sun would raise soon, so I didn't go on observated meteors.
I'll observate in next two days if the weather is fine, and could I ask you a question: There're 10 STO meteors per hour and there're 10 STO meteors per night, which is right?
Cheers,
Ye

昨天天氣不錯的說
一出陽台就見到兩顆群內流星。英文
不错！可好象还没到日子…… 对，对于没耐心的人是还没到日子。这么几颗几颗的，太慢了……
IMO主席R.Arlt昨天晚上回信了
Dear Ye,Many thanks for the observing reports. It's sad that
you have to observe under such low lm. Since the Visual
Meteor Database sets a limit of +4, I will probably use
only the last observing period. I will be nevertheless
glad if you continue your observing efforts. Let's
hope for good weather tonight!
Best wishes,
Rainer
今天早晨有个不错的LM，但是天气不好，才看到4个！ 昨天晚上，试相机，看到一颗0等GEM流星。
准备今天大干一场，结果天现在阴了，只好听天由命了。
