              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The night was unexpectedly nice, with no threatening weather, clear skies much of the time (okay, and partly cloudy skies some of the time as well), and good seeing.  We were able to open before sunset and stay open all night.
The visiting instrument observed four planets, but ran out of targets before morning twilight, so I took the last hour to check collimation with the Shack-Hartmann.  It's unusual to get an opportunity to use Shack with the telescope fully cooled down.  I did not make any changes to the collimation.
