 Observing Specialist: J.Dembicky
Spicam temp at start of night 178.8K
Spicam temp 173.2K at 02:00
UW15 and UW08 did a swap tonight since it wasn't photometric.  UW08 finished a little early and
gave the remaining time to JH01.
We lost about an hours worth of time at various points during the first half due to clouds.
Clouds again at 01:40 and radar echos getting near around 02:00 (when I closed).
Called it a night at 04:30 with clouds and radar returns nearby, but no precip yet.
No telescope problems tonight.
