Some extremely high errors in these visual observations and these 
ZHR's do not seem to match those from other observers' data in the 
United States, including California. You can not judge a meteor 
shower's visual strength by such hit and miss observations.

Since the prediction was for faint meteors I can see the reason for 
the use of intensified video cameras. But how does the data from 
these cameras compare with other video intensified observations of 
the Ursids from previous years? I would be very interested in seeing 
what the "normal" rate would be for the Ursids with such equipment.
