(meteorobs) Video Observations from Southern CA, December 17, 2009

[Robert Lunsford]

The cirrus was less widespread than yesterday. It was more prevalent during the evening hours and then cleared during the morning 
hours. It's puzzling to see the dip in rates between 11-12 UT when it was mostly clear. It's also surprising not to see any 
Antihelions prior to midnight, as the radiant is high in the sky.
