                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 No problems tonight.  We had a humidity spike around midnight and the
 seeing went to 2-3 arc sec as a cold front passed over us, but it never
 quite reached closing levels.  The winds then changed back and the seeing
 improved around 2AM.
