                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
   I opened the enclosure at 15:30 to start cooling. The Goddard F-P
instrument was allowed to warm today until its next use. No troubles
encountered, skies were clear and temps cold and seeing bad. The GrIm
application quit at around 20:50 MST and the ICC was rebooted
successfully.
 Observing Specialist, 2nd Shift: Russet McMillan
 Second half had its share of annoyances -- wind gusts, a dust spike,
 continued horrible seeing (3.5-5 arcsec), and computer troubles at
 the NMSU end which made it difficult for the observer to monitor
 image quality.  A second failure of the GRIM application cost a few
 minutes.  The telescope was closed shortly before 0400 due to
 persistent high winds.

 is north=0 degrees, east=90 degrees.  The dust count is particles > 1u
