(meteorobs) Video Observations from Southern CA, December 18, 2009

[Robert Lunsford]

The cirrus clouds were back tonight with vengeance. It was mostly cloudy until 11UT (3am PST). The next hour seemed to be totally 
clear and then clouds interfered again the next hour. The last 46 minutes had mostly clear skies again. The new "COM's" have been a 
disappointment. They are supposed to be slightly weaker than the "DLM's" but the difference to me is striking with the "DLM's" being 
the far stronger shower. Note that the first Ursid was detected tonight.

As the sun sets on another day it appears that I will be battling cirrus again tonight. Oh well, at least I can obtain a little data 
instead of none at all!
