                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was opened at 18:00.  It was closed for a little while
during UC03 for humidity.  The observers were Gordon Richards for
Adler (UC12), Salman Hameed and Nick Devereux for NM04, myself for
PU01, and Dan VandenBerk for UC03.
I had to change filters and instruments at sunset, which must be my
fault.  So there wasn't much twilight time after that.
			     OBSERVER COMMENTS
Dan (UC03) - Weather was generally good, clear, except humidity was
high enough to close once. Remark didn't crash all night! James
Rhoads' random dither script 'dsrand' seemed to work well once we got
it started - - it seems it is best to run this in a separate mcnode
session when running remark. Seeing was apparently quite good
(0.77arcsec) but I would have to measure this from the frames to see
if this held through the night.
