                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: R.McMillan
 Tonight had clear skies and excellent seeing (the values in the
 focus log are estimates by eye, rather than measurements).  CorMASS
 was brought back to working condition again today, and many
 productive observations were made first half.  Everything worked
 fairly well; most cold-related problems from last night disappeared
 with the milder weather.
 2nd Half Observing Specialist: J.Dembicky
 No problems 2nd half.
