                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was opened at 21:45 MST; opening was delayed by clouds.
It was closed at 01:10 MST, due to humidity, and reopened at 02:55
MST.
The observers were Jeff Secker for WS02 and myself for PU01.
The weather was quite cloudy much of the evening, then humid after the
sky cleared.
			     OBSERVER COMMENTS
Jeff (WS02) - (1/29) "SPIcam worked well as usual.  One note concerns
an unusual message which appeared immediately after the
initialization, before the spicam: prompt.  It said:
cat: cannot open .motd
Waited for heavy cloud cover to clear. Opened around 10:15pm and
focused.  Seeing of about 1.1 arcsec in R.  However, heavy and
variable cloud cover prevented me from obtaining any useful
images.  Closed up shop 20 minutes early."
Jeff (WS02) - (1/30) "The enclosure was closed for about four hours
due to heavy cloud cover and later due to humidity, and the seeing was
not very good.  In addition, I had unrelenting network problems.
However, SPIcam and the guider both worked flawlessly, and I was able
to get a useful set of images."
