              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear first half, with increasing high clouds during second half, but we were able to observe all night.  The onsite class got some good data.  At one point during second half the guide loop (but not the guide camera?) got hung up, so it would take individual images but would stop guiding after a single image.This was quickly fixed by restarting the gacm nub, so very little time lost.
