              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
GIFS hold time 13.75 hrs tonight.  Mostly info for the obs specs as the nights are getting longer and so are the time between fills.
We had rain in the afternoon, and then cloudy most of the remainder of the night.  I opted to stay closed due to a band of darker clouds, on the satlellite, slowly moving over us.  The sky started to improve about 45 mins before the start of twilight (or a sucker hole) but we still had a good layer of uniform cirrus with a lot of extinction.
