                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
    When I arrived today the winds were very high and delayed opening. I
worked with Jon Holtzman on measurements of the guider filters for the
upcoming upgrade.
    Wind died enough for us to open at 18:58 MST. The seeing was decent
despite the high winds and warm temps. Immediately upon starting, at
about 21:15 MST I think, the MC halted and the Obs-2 Mac crashed. I
restarted them both and we quickly started another exposure.
    Final program of first half started without troubles and ran smoothly
for remainder of my shift.
 Observing Specialist, 2nd Shift: Russet McMillan
 Near the end of first half, the echelle observer had some trouble
 when a series of commands to pause and then resume the exposure (due
 to clouds) apparently messed up the echelle's readout time.  The
 exposure was not completely lost, but did have some contamination
 because the shutter was open at least part of the time when we
 thought it was closed.  The observer quit a little early because he
 wasn't getting much through the clouds.
 Second half was also challenged by variable cirrus, sometimes making
 guiding impossible, but many usable spectra were obtained and the
 telescope never had to be closed.  The seeing (when measurable) was
 good to moderate (0.7-1.4 arcsec, with a dependence on azimuth in
 comparison to the wind direction).  There were no serious troubles,
 and I finally managed to diagnose the recent problem we've been
 having with pointing corrections, so that should become much less of
 a time sink.

  note: the wind was coming from the azimuth listed.  The convention
  used is north=0 degrees, east=90 degrees.  The dust count is particles
  > 1u per 0.1 cubic feet.
