              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Well, we weren't so lucky tonight.  The afternoon had snow/sleet/rain/grapple, all the cold stuff. It continued for a few hours but there was no snow accumulation.  When it wasn't wet it was just complete overcast and pretty much humid the whole night and we did not open.  We used the time for UV02 training so hopefully everything will go off without a hitch on Tuesday.
During checkout I noticed that the rotator was off by about 5 degrees.  I zeroed it out (Set.Position of 2.705) and didn't have any further problems.  I'm not sure what happened as I didn't have any issues last night and was the first to move it this afternoon. ARCTIC was left parked with a rotation of about -150 when I closed up yesterday. A problem report was sent.
