[观测日记]今天早晨的观测成果

可能由于数学成绩不错，我终于获得允许可以在周边5公里内找一个地方观测流星雨。不幸的是，前几天很好的天突然变成了阴天，但我还是决定碰运气。晚上11点多，我出发了，在寒风中坚守到了3点，但是天气一直不好。当我正打算回家的时候，天气逐渐晴朗，我又决定继续观测。终于，3：23，一颗-2等的火流星不紧不慢地在天空中滑过。3：25出现了两颗流星，3：30和3：42各一颗。3：45以后，天气又开始变坏，我停止了观测。

以下是发给IMO的报告：
Dear Rainer,
 I had to stay at home to observate Geminids because I must go to school tomorrow. Today and tomorrow I needn't go to school, so of cause I can go out to watch. Unfortunate, the weather went bad last night, so I decided to take my chance. I waited and waited in the cold night, but there were still cloudy. At 3:00AM I could not bear it, and I decided to go home. At that moment, the sky began to clearness. So I went on watching. I observated only five meteors this night, two were fireball. The weather began to cloudy again afther 3:45AM, so I had to stopped.
 I'll watch it tonight if it's fine. Here're my report, the LM is better.
