                ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Dembicky
 Dust conditions kept us closed until 20:45.
 Seeing was poor at the start of the night for the first couple of hours.
 I adjusted the focus off the guider.  I checked it at around midnight and
 seeing was around 1.3 arc sec.
 The wind direction changed around 01:00 and the seeing degraded with it,
 between 2 - 3 arc sec. I tweaked the focus as best I could from the
 guider.
 Everything ran smoothly tonight.
