              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The night was clear with good seeing, and mostly peaceful.  There was one unexplained telescope jump which did not require stoppnig an exposure but did cost some photons.  ARCSAT needed a reboot.  And the APOLLO chiller was still misbehaving, so the time originally scheduled for APOLLO was given to the adjacent program.
