              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We had clouds most of the first half, with a few sucker holes.  We finially opened at 00:35 and were able to get about 30 mins of data before clouds came over us just as the first half program finished.  I used a bright star to focus the Echelle for the 2nd half, and then handed the telescope to that program.  It looks like this is the last band of clouds and hopefully clear skies afterwards.
Closed at 02:30 due to a few raindrops in the area.
Radar showed possible precipitation to our west until around 05:00, at which time there was not enought time left for the 2nd half observer to get any useful data, so we called it for the night at that point.
