                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Snow started falling this afternoon around checkout time and continued
intermittently after dark, preventing us from opening.  I ran the snow
program from the time it first started snowing.... better luck tomorrow.
 2nd Half Observing Specialist: R.McMillan
 Windspeeds and humidity remained high until about 03:30, and when
 they dropped there was still just a little too much snow on the roof
 to permit opening.
