observing specialist:  Karen Gloria
The telescope was opened at 17:30 MST.  It was a clear, photometric
night.  The seeing was a bit below average at the beginning of the
night, but improved to 1.0 arcsec.  The telescope pointing was very
good.  Nearly all of the targets landed right on the slit of the
spectrograph.  Telescope tracking was tremendously improved over last
night's performance, thanks to the efforts of the day staff.
The PU01 lens monitoring run went well.  Scott Austin (WS02) had a
productive run doing spectroscopy.  Elizabeth Rizza (NM02) also
obtained good spectroscopic images of some rather faint targets.  With
the conditions being photometric Elizabeth and I decided to put SPIcam
on to image some of the targets she missed last night when we were
having trouble with the telescope tracking.  We tried drift scanning,
but kept getting short trails.  Maybe some of tonight's engineering
time can be used to investigate what went wrong there.  After a few
failed attempts at drift scanning, we decided to just take staring
frames, which worked out OK.
                             OBSERVER COMMENTS
NM02 (Rizza):  Everything seemed to go smoothly, except for the
problem with the drift scanning.
