              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Had to restart the gcamera icc computer this afternoon because it wasn't pingable.
We had pretty good seeing and only a few thin clouds, and no other instrument or telescope problems.
Temperatures were mostly a few degrees above 0C, humidity around 10-20%.
