                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clouds and high winds and dust and fog and snow, with a few inches
 of accumulation including some on the dome.  I didn't turn on the
 roof heaters because temperatures were too low for them to be
 effective.  I worked on the Q2 work schedule and some more
 bookkeeping.
