                  ------------- ACTIVITY LOG --------------
 2nd Half Observing Specialist: R.McMillan
 The night had lower dust levels and less wind than recently.  Skies
 were clear part of the time, with a few banks of passing cirrus which
 grew thicker toward dawn.  The seeing was rather poor (1.5") until
 the telescope finished cooling; after that it ranged from 0.7" to
 1.2".
 We had a few minor difficulties; one readout problem with the red
 chip that fortunately affected only an unused part of the image, and
 a tendency for the red spectra to be slightly out of focus compared
 to the blue (or the slitviewer).  We should have a chance to address
 these issues next week.  Neither of these problems cost any time, and
 the observer got some interesting spectra.

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