              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
Another photometric night with good seeing, this time with no high winds.
Multiple crashes of the echelle slitviewer software caused difficulty
with the first program; we made some progress on diagnosis and found
some workarounds to streamline recovery, but a real fix is still needed.
NICFPS had one image-block problem when turned upside-down; although the
problem was promptly identified and corrected, we didn't realize at once
that the reset had also changed the fowler sampling, so a couple of
dithers had to be repeated after the settings were corrected.
