              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan,A.Shugart
Rain and clouds in the evening, but we were able to open before midnight.
Seeing was initially poor but got better later in the morning.  Humidity
rose near the limit and I pushed it for a while but finally had to cut off
the observer's chance of getting twilight flats.
DIS is having an odd problem with apparent dark current on the red side
even though the red chip is colder than the blue (which has no trouble).
There was a false fire alarm at 04:50 from the new dorm; Audrey and I
silenced and reset it.
