> The #03 meteor is quite probably to be simultaneously observed by Mr.
Tielei
> Xie in another observation compaign near Tai Mountain which is about 500
> km (?) south of Xinglong. He called me by mobile telephone as soon as he
> saw a -1 meteor going southwest from Vega, and it was just about seconds
> when we saw a -1 meteor coming down near the south horizon. Both the time
> and brightness are very similar, and the different directions for
> the two sites seems also reasonable. However, Mr. Xie may not prepared for
> a complete observation report this time.
