              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Got back on sky after the telescope was disassesmbled and reassembled
-weather was near-photometric with very good seeing.  I did a rough
collimation, but wasn't ready for Shack-Hartmann until the telescope
cooled more, so while cooling I took some throughput data with SPIcam.
Weather was not perfectly photometric but rarely gets better this time of
year.  I hope the data will be sufficient to answer some questions about
instrumental zeropoint.
Collimation with the Shack-Hartmann was quick and easy.  Pointing was
somewhat more vexed - I took a short model and a long one, and we might
need to make some more adjustments based on those results.  So, work still
needs to be done to get the telescope in a fit state for science, but we
made a lot of progress tonight.
