                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I started cooling the telescope (fans and louvers) around 16:30 tonight.
 Clouds prevented me from opening the enclosure until 21:30.
 Other than a interval of thicker clouds around 03:15-03:45, which they
 observed thru, the 2nd half observers were able to stay on their target
 all night long with lots of data.
