              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
There was a scheduling gap of one hour.  I split the time between AD02 and UW02, making to swap time 00:40.
In the afternoon, gcam and ecam were both unhappy.  Fritz logged in and found some typos, which he fixed.  Everything worked well after that.
We had good seeing, with clouds that came and went.  During second half, a threatening system rolled in, and we closed up.  It never cleared enough to open the rest of the night.  We gave up at 5:00.
