                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 No problems tonight but poor seeing in the 1.5-3.0+ arc sec range.  I
 adjusted the focus on the fly while the observers were running DIS
 during the first half.  Not much helped with such poor seeing. The
 winds kicked up around midnight and became too gusty at 03:00 to observe
 anymore.
 We gave up around 04:45 when the sustained wind speeds topped 50MPH.
