              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We remained closed at the start of the night due to clouds.  We opened about 1hr after sunset.  We fought clouds most of the night, even though the satellite showed we were in clear sky, must have been local clouds because they were outside.
No problems with the telescope tonight.
