                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Opened again at 17:00 under clear skies.  The echelle slitviewer crashed
for the first time at about 18:45;  fortunately, recovery was quick.  The
second crash happened about 15 minutes later, then a third at 20:05.  The
leading edge of a storm system moving in from Arizona arrived shortly
after 20:00.  By 21:00 the sky was soup and precipitation threatened from
the west, so I opted to close.
 2nd Half Observing Specialist: R.McMillan
 Clouds all second half.
