              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had snow and blowing snow all night, but it wasn't as bad as it looked on radar.  Most of the flakes were moving sideways, and there was less than half an inch of accumulation by morning.  Under that half inch of snow, however, was a half inch of ice.
I did not run the snow program because the dome was struggling against the wind during test slews in the afternoon, so I just moved to a few different azimuth positions at times when the wind was lighter.  Electricity was pretty steady all night, which was very nice.
I worked on calibrations for NICFPS in grism mode, and methods for tracking contamination on DIS.
