                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Dust and wind kept us closed until the end of twilight.  No problems
 otherwise.  Seeing was poor at the start of the night but improved as the
 front moved to our east.  I tweaked focus on the fly for both the Echelle
 and DIS.
