                  ------------- ACTIVITY LOG --------------
   Observing Specialists: J.Dembicky, J.Barentine
   Weather again prevented all observations tonight.  First half was
entirely clouded out; clearing occurred late in the second half but high
humdity prevented opening.  Humidity was high all night coupled with
intermittent 1um dust density spikes.
