              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started off nice and clear but clouds rolled in around midnight.  They became too thick to see even the moon.  There was radar near by so we decided to close.  I tried opening again before 5am but there was still enough cloud to keep me from focusing tspec.  As the observer required at least one hour of observation I decided to give up at 05:10 when I was still unable to focus.
There was a problem with the ARCTIC shutter and it needed to be reset.  Once it was reset it worked fine.
