              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Weather was beautiful at the start of the night, with clouds staying to the south of us and smoke staying to the north.  So I prioritized throughput for the first half engineering.  Second half I updated the Tspec inst block, did some tests to try to reproduce pointing errors, and fixed collimation.  Then I had to close for a smoke spike, but all around it was a pretty productive night.
