              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had clear skies first half and increasing clouds second half, with mediocre seeing.  The second half observer gave up trying to shoot through clouds about half an hour before twilight.  Everything worked well on the 3.5m.
Everything worked well on ARCSAT too... up until the observer closed and tried to park the dome, then it reported a bad position or stalled dome motor.  Also, the webcam did not appear to be working.
