              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out completely overcast.  There were thicker clouds coming to the west approaching and I was worried that they might condense when they hit the mountain ridge so I did not open.  However, Russet convinced me at 18:52 and we were able to see stars. We remained open as long as we could hoping to catch holes but much of the time was lost in the clouds. We closed at 00:55 due to weather and rain on the radar.  The rain never reached us but it stayed cloudy the rest of the night.
Tspec was behaving badly.  I ran a power cycle and left it inverted but there was no improvement.
