(* means a trouble report has been issued or appended to)
1st half observing specialist: Loomis
The telescope was opened at 16:30 MST under clear skies.  I observed
for UW07.  Afterwards, Jeff Morgan, Craig Loomis, Frank Deglman, and
myself took Shack-Hartmann data.  This went every well, with only
minor glitches.
2nd half observing specialist: McMillan
Second half started out clear with very poor seeing.  Clouds began to
move in around 03:30, and we closed at 05:10 due to clouds.  Some
useful data was obtained, although the signal was low due to the loss
from seeing and the fluctuating air temperatures which degraded
focus.  We also saw some examples of windshake moving the telescope up
to 10 arcsec when pointed at high altitude near a 25 mph wind.
We lost some time due to a need to re-home the gratings after the
first exposure came out wrong, and * a mysterious deadlock in the TCC
that caused tracking to stop for unknown reasons.
