                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 The enclosure remained closed all night due to substantial amounts of
snow and ice on the roof.  There was some clear sky early in the evening
but it became overcast later on; high humidity, in any case, would have
prevented opening.
 2nd Half Observing Specialist: R.McMillan
