              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden, R.McMillan
High winds and really AWFUL seeing throughout the night.  Opened at sunset, and then things got dicey after 20:00.  Closed, reopened for an hour, and closed again.  Did not open again, and gave up at 05:15
Because of the awful seeing, there wasn't much we could do.  We did the ecam tests as requested, fixed pointing on NA1, took a bunch of throughput measurements, and attempted to check collimation.  This one proved to be impossible, as the primary never equilibrated with the outside temperatures, and when we tried the seeing and wind shake were beyond the Sensoft ability to fit properly.  We also homed the secondary.  Took some test exposures for Tspec for the Dim Quartz filters.  They are in the engineering directory under tspec.
Power was stable, spicam space heater is left ON.  Tspec is mounted on the telescope.
