              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I had to cycle the mirror cover switch.  Eyelids would open via remote control but not the covers.
A thunderstorm and a little rain around 19:00.  It was cloudy most of the night, we had a few sucker holes appearing after around 3:30ish.  From looking at the satellite things were still looking pretty dicey to open just yet, especially since this system had precipitation in it earlier, so I held off until I felt more comfortable.
I finally was able to open at around 04:30.  I got an alt motion error on my initial slew (at 74.5 deg, it was at 75deg).  I power cycled the drives and that cleared the issue.
