 Observing Specialist: J.Dembicky
 I started cooling fans around 15:50.  Traing the CU folks tonight on the
 telescope. We opened around 19:10 under marginal conditions, and just
 about long enough to get focused before the clouds rolled in and killed
 us before any useful science could be obtained.
 We closed at 20:15 due to clouds and the threat of snow on it's way from
 the west.  The rain sensor (or snow sensor in this case) went off around
 03:00.  Just flakes in the air so the snow program was not run.
