              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
High winds and borderline dust before sunset improved for us to get on the
sky, but thick clouds moved in soon after.  The dome stayed open until
nearly midnight, but the observers were getting nothing at all for several
hours.  Then radar moved into the area, and I closed for a while.
While the dome was closed, I was able to do some testing with APOLLO to
answer a longstanding question.  Then the radar and clouds left the area
so we could open for some comet observations, including how the new guide
software dealt with nonsidereal tracking.  So, despite losing several
hours to weather, it was a somewhat productive night.
