                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 My xterm client window that had my Pine session closed on me, in Jeppe,
 and somehow Galileo didn't recover the e-mail when I restarted it.  I'll
 do the best I can from memory of what Russet and I did the first part of
 the night.
 Russet zero'ed the rotator during the afternoon.
 Since we needed to wait for the telescope to cool down, we gave soem time
 to the Agile (UW02) folks to do some tests on the U filter installed in
 the camera.  It seems that the camera was not too sensitive to UV.  Good
 info to know for tommorow nights run.
 Russet then used the S-H to check/adjust telescope tracking.
 Unfortunately the numbers she gave me were in the e-mail the got axed.
 By this time the telescope had cooled enough that we could do collimation
 tests/refinements.  Russet also did an S-H altitude sweep.
 I did a 80 point pointing model, 1 bad point due to a bright star which I
 removed, and implemented that model.
