              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Started the night with heavy clouds, lots of humidity and wind, and a little bit of snow.  The clouds cleared quickly, but the humidity and wind stuck around for a while.  We were eventually able to open, but we had poor seeing.  I took advantage of the high winds, and took dome air flow data.  Details in the email.
In addition:
zeroed the rotator
reset axes controllers
took tspec data
took ARCTIC darks
tested ARCTIC filter wheels and updated PR
updated/edited documentation (mostly NICFPS and some housecleaning items)
short pointing model, reduced by not implemented.
