              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A dramatic thunderstorm in the afternoon cleared up nicely by sunset, and
we were able to start observing promptly.  Humidity was near the limit but
with the telescope fairly warm I felt safe in pushing the humidity limit
for a while.  However, seeing was poor to awful and thin clouds gradually
increased, until it just wasn't worth it to keep pushing the humidity.  We
closed for several hours.
When the sky and humidity both improved a little, we reopened, but the
telescope was having problems moving in altitude.  It might have been a
moth, or it might have been the large change in temperature destabilizing
the system.  The problem was bad enough that I couldn't even move the
telescope to clean the moth guts away.  By this time there was about an
hour and a half until twilight and the observer didn't think she would be
able to get science even if we woke someone up to work on the telescope,
so we called it for the rest of the night.
I used the bypass to allow ARCSAT to stay open after the 3.5m dome was
closed.
