              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Tonight was a lovely clear night with warmer temperatures than the last week or so.  Seeing was moderate despite wind in the east.
Everything worked well except for the main observing computer obs1, which started misbehaving in the small hours for the sixth Sunday in a row.
