                  ------------- ACTIVITY LOG --------------
 Observing Specialist: John Barentine, Jack Dembicky
 The telescope fans were turned on at 18:10
We were training Colorado observers tonight on DIS. The observers
started taking biases and flats at 19:45 under mostly clear skies.
Observers were taking their first science images by 20:05.  Seeing was
mediocre at the start of the evening and improved at times to sub arc
second by the middle of the night.  By the end of the night the seeing
really got worse with readings in the 2 to 3+ arc sec range.
Despite the poor seeing the Colorado folks got some good data with
DIS tonight.
