                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
1st half observing specialist: Karen Gloria
The telescope was opened at 17:40 MST and closed at 20:30 MST due to
clouds.  Based on the weather forecast, Scott Anderson decided to run
his backup, spectroscopy program instead of the photometry.  He and
Xiaohui Fan (observing from Princeton) were able to get to a couple
targets before the clouds got too bad.
2nd half observing specialist: Russet McMillan
Second half remained cloudy.  I closed the cloud camera at 03:30 since
radar was showing precipitation not far away, but nothing actaully
came down here.
                            OBSERVER COMMENTS
S.Anderson (UW10):
Lots of clouds were drifting by, but we got some useful data early in
the evening before closing for most of the remainder of the first half.
We also got a brief slice (useful though) of additional time on the sky
near the end of the first-half, thanks to Karen's careful attention to
conditions. Instrument (DIS/low res), telescope, and APO staff
support were excellent.
