                 ------------- ACTIVITY LOG --------------
 Observing Specialist: N.C.Hastings, J.Barentine
    Opened at 18:40 MDT to allow for cooling. All ran smooth for Adler and
both Echelle programs tonight. Telescope behaved well, seeing was not too
great.
    At 00:19:24 there was a major glitch in the autoguiding routine. Some
info was spewed across the MC screen and then we made a 2,000,000 arcsec
offset. Oops. We paused exposure, re-acquired and all was fine after that.
    Don York reported that second half the telescope was making many small
movements of about 0.1 arcsec and that later many of these offsets were in
one direction predominantly.
    Seeing improved much around 04:00 and all seemed to run smoothly.

  used is north=0 degrees, east=90 degrees.  The dust count is particles
  > 1u per 0.1 cubic feet.
