                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Snow and wind earlier in the afternoon foretold poor chances of opening.
Skies briefly cleared up considerably around sunset but the winds kept
hovering around the closure condition.  Near 20:00 the partly cloudy skies
went overcast and remained that way for the rest of the first half.
 2nd Half Observing Specialist: J.Dembicky
 The skies, humidity, and dust finally cooperated around 02:00 and allowed
 us to open to partly cloudy skies.
