              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The night was mostly photometric, with mostly good seeing.  Unfortunately, ARCSAT got hung up very badly and wasn't able to recover even with help from Jack.  But the 3.5m and echelle behaved pretty well, aside from one motion error at 20:36, slewing downward, stopped around 53 deg - this seems to be a recurring problem spot.
