                ------------- ACTIVITY LOG --------------
Observing Specialist: Russet McMillan
Heavy rain in the afternoon.  Light rain in the evening.  A sucker
hole at midnight (I even tried opening, but stayed in the dome and
closed within about five minutes when it was clear we couldn't get
anything through the clouds.)  Heavy rain again in the morning.
In the morning I closed the valve feeding nitrogen to the echelle
CCD, in preparation for trying to bake some contamination off the
chip during the day.
