                ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
More snow, blowing snow, high winds, high humidity.  I ran the snow
program for a few hours until a power outage tripped an interlock I
was unable to clear.  The telescope is facing north.  The power
outage also triggered another warmup for DIS, again into the mid-70s.
I investigated a non-thermal dark current issue with DIS, evaluated a
potential new flat-field paint with SPIcam, and did some aliveness
tests of CorMASS.
