                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was opened at 16:15 MST.
The observers were Ted Wyder and Dan Zucker for UW10, David Reiss for
UW04, Russet McMillan for PU05, and myself for EN02.
The seeing was fair (about 1.5 arcsec) at the beginning of the night,
but gradually improved to 0.9 arcsec in V.  High clouds began to
appear at 22:15 MST.  There were no problems with the telescope or
instruments, aside from the SPIcam autofill timer.
Reiss (UW04) and Stubbs (UW02) swapped their time slots.  Stubbs gave
UW02 time to EN02 in order to test the stability of the DIS line
positions.  For this, I observed a radial velocity standard high and
near the meridian.  Cals were taken immediately following the
observation of the star.  This process was repeated for a different
rotation angle.
			     OBSERVER COMMENTS
Wyder (UW10) - (forgot to ask for comments, but he did comment during
his run that everything was going well)
Reiss (UW04) - (ditto)
McMillan (PU05) - (ditto)
myself (UW02) - Taking cals in between object spectra uses a lot of
time.  Much of this spent going back and forth, forth and back to the
telescope to open and close the mirror covers (plus setting up a
ladder to reach the controls).
