                  ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The night was mostly clear, with some very sparse clouds passing much
 of the time and one period of thicker clouds.  Seeing was very good;
 the echelle was getting 1 arcsecond at three airmasses, and better at
 more reasonable positions.  The echelle pointing was excellent, and
 everything worked well aside from a crash of the slitviewer Mac; it
 was rebooted without no interruption to observations.
