(meteorobs) Post peak Geminid chunks- some larger?

[cookewj at comcast.net]

Our fireball cams have recorded 38 multistation Geminids so far this year. If I look at the magnitudes, I find that 


Average peak magnitude for 12/13 - 12/14: -2.4 +/- 0.7 (1 standard deviation) 
Average peak magnitude for 12/14 - 12/15: -3.2 +/- 1.4 (1 standard deviation) 


The averages would indicate that the Geminids were larger last night, but there is considerable scatter.

I wonder if there is a pattern of the occurrence of larger magnitude 
post-peak Geminid fireballs ? 

Here is a nice one from last night. Dec 15, 2011 at 0646:01 UT.
