                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Another quiet night of clear skies and mostly good seeing.  Dust was
 elevated first half but not beyond the point where it could be
 controlled with fans, and it dropped as the evening progressed.
 Everything worked well.
