              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Delayed opening due to clouds.
Humidity rose during the second half of the night but we remained open, even with the pesky orographic clouds.
The last program really got clobbered by the borderline humidity and the local orographic clouds really prevented getting any useful data at all.  I chalked the time up to loss due to weather even though we did have the dome open.  We got about 10 mins of one star and then the humidity just got too bad, along with the clouds, and I decided to call it for the night at 04:40.
