                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I opened the enclosure for cooling around 16:30 tonight.
 My observer logged in a little early tonight to get a feel for using
 NIC-FPS.  After a few minor glitches we he got going.  Stephane B. Logged
 in because of the filter wheel problem reported last night and we
 discovered that the mask was not in the proper position to do darks (30
 sec darks showed a definate gradient).  Stephane worked on while I did my
 final test slews.  He got things working properly and we were on the sky
 focusing around 17:45.  Stephane told us that they would take care of
 filter changes from Colorado tonight.
 We had a small ICC problem while Stephane was changing filters at 19:40
 and couldn't communicate with the program.  Stephane had me exit the
 program and restarted and all was well again.
 Humidity shot over the limit around 21:20 and forced us to close.
 The dew point depression never climbed above the 2.2 deg limit for the
 remainder of the night (Actually the outside air temp rose as well as the
 dewpoint and with a closed dome the secondary become colder than the
 dewpoint at one time.  I places a heater on the floor under the secondary
 cage to try to warm things up a little).

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
