(meteorobs) Obs. 2000 Nov. 17/18 (Huan Meng)
Note: I will send in the next one hour 6 observational reports by
different individuals made at the Xinglong station, Beijing Astronomical
Observatory for the previous night (17/18). It is cloudy now and there
might also be cloudy for tomorrow night. It seems that we had more brighter
meteors here in China? - Jin Zhu
