(meteorobs) Dense Bright Meteors`of Quadrantids

[0472042 at fudan.edu.cn]

Hi,all!

Yesterday my friend Qiang Ma told me that he and Mengling Zhang make 
observations during 20:45-21:52(UT) on 3/4 night. And they observed 
many bright meteors in there 1 hour and 7 minutes' observation. Both of 
their lm is higher than 5.2. And k is only 10%.

They observed 16 meteors brighter than -1 mag. and 10 of them are at 
least as bright as -3 mag while the total number of QUA is 31.

Qiang Ma's observation's Mag. distribution is
mag.	-5 -4 -3 -2 -1 0 1 2 3 4 5
number	 1  2  7  6  1 1 7 3 1 2 0

(The detail reports will be sent here soon.)

I calculated the population index from his data. the preliminary result 
is 1.90 and the corresponding ZHR is about 90.

As they told me, after they finished their recording, they also saw 
many bright meteors, and it seems that the bright meteor appeared more 
frequently.

Do anyone make observations in the surrounding periods (especially the 
later periods)? 

Or any other informations about this?

Clear Skies!
