(* means a trouble report has been issued or appended to)
The telescope was opened at 19:00 after calibration images were taken.
The telescope was closed from 21:30 to 23:15 MST, due to high
humidity.  The sky was partly cloudy most of the night, with
predominantly high clouds.  The observers were Charles Hoopes for
NM07, myself for PU01, and Russet McMillan for UC02.
Remark will need to be updated to work with the newly revised version
of the DIS software.  There are some new DIS keywords and for some
reason Remark wasn't seeing the turret keyword (which hasn't changed).
Charles and I discovered this during his observations.  Robert Lupton
reverted to the previous version of the software.  He will send email
to Bob Loewenstein with the details needed for Remark.
I pumped SPIcam for another hour this morning and began cooling at
7:00 MST.
			     OBSERVER COMMENTS
Charles (NM07) - "We lost a lot of time to humidity, and had some
clouds even while we were open. We got a little data on diffuse
ionized gas in M81, but not much. Lost a little time to a software
glitch with DIS."
Russet (UC02) - "Everything went well."

used is north=0 degrees, east=90 degrees. The dust count is particles
> 1 micron per 0.1 cu. ft.
