              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I had to do a nubs restart on gcamera tonight.
We had a problem with ARCTIC mis-aligning the filters tonight.  Took me about 45 mins to diagnose the problem.  (I counted it as 0.4 hrs loss as they could not finish their flats before the start of their program and we needed to go into twilight time.  One of the filter screws was about 2mm too long and sticking out the back of the filter plate which caused all the problems.  Unfortunately, after I removed the long screw and replaced it with a shorter one, the sensor then would not read the wheel correctly. It kept reporting as filter wheel #3.  I fudged this by simply copying filter wheel #7 filters to wheel #3 and we were good to go.
We closed at 05:00 due to high winds (and clouds too, but mostly wind) and my observers last and only target was pointing directly into the wind.
