(meteorobs) Perseids on Aug.10-13, China

Sat Aug 14 05:57:56 EDT 2004

Hi all,
  I was out for Perseids on Aug.10-13, to one of my
best sites -- Xiaoshan town. The sky was so so on
10/11, but it become much worse on Aug.11 because of
the typhoon. So on 11/12 it was raining, and I was
unable to catch the rev-1 peak. Fortunately, the sky
become prefectly clear on Aug.12, so I observed 234
Perseids during the wonderful night. The brightest one
was a fireball appeared on 20:34UT, which magnitude to
be -8. 
 Clear skies,
Quanzhi
