              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out with some problems.  The azimuth controller was not communicating over the network to the CSS so we didn't slew.  However, we only lost about 30 min of twilight time.  Seeing was pretty good considering the higher winds we experienced but the clouds were rather annoying.
Dcam started acting up again and Russet turned the temperature up a little and it behaved better.  It was difficult tracking given the faint objects but we were able to go so.
