               ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage, J.Coughlin
Operations were nominal for most of the night. At instrument check-out
nicfps was reading all 65k counts, but this was fixed with a nicfps
expose init. DIS slitviewer hung up 5-6 times and was fixed each time
with a hub startNubs dcam.
Clouds rolled in around 9:30pm and stayed until 2am. During the down
time we created a new DIS slit mask and observers took calibrations.
After the clouds cleared, relatively high winds and poor seeing
persisted until morning, but we remained open and observations were
taken.
