              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
This high clouds all night, occasionally enough to cause some trouble on
high-airmass targets.  Seeing was good during first half but less good
second half.
The gcamera needed to be power cycled again today; it seems this is
occurring more frequently.  There was also one incident of nasty
oscillations on the altitude axis in the middle of a slew.  The altitude
seemed fine after being re-initialized, so the time lost was really just
for me to check things out and document what had happened.
The scheduled second half observer didn't send a setup email or log in,
and there was no phone number in the proposal.  Since the first half
observer was also from Princeton. I let them continue observing longer,
and they found me another Princeton observer who was awake and available
to make use of second half.
