              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley, R.McMillan
I was delayed opening because of some clouds and nearby radar returns.  Jon was working on the tcc anyway, so I don't count this as time lost to weather.  Jon was unable to get the tcc to backup.
I did the dis focus tests, a large NA2 pointing model, small NA1 pointing model, and attempted some throughput measurements.  These were done in occaasionally cloudy skies.  Heavy clouds and nearby radar returns forced me to close at about 03:00.  The weather never improved, and I gave up at 05:30.
