                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 A loss of power early in the afternoon resulted in failure of
 the amplifier on the altitude axis. Nick, Dave and Mark worked
 for several hours to replace it.
 Snowy conditions in the afternoon followed by overcast skies and
 high humidity the rest of the night. Around 00:30 snow again started
 to fall and by morning we had over an inch on the ground. The
 snow program ran all night. The first half observers were able to
 get some test data using the flat field lamps.
