              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds most of the night.  We were able to observe with the spectrograph and optical instruments but the clouds interfered with the IR instruments.  THe clouds started to clear out around 02:40 and we were finally able to start to collect IR data.   We stayed open all night but lost about 2.5 hrs due to clouds with NICFIPS.
