              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
A peaceful night with clear skies and moderate seeing.  The instruments
and telescope behaved well.  I was also working with the echelle, which
has been freshly re-cooled after pumping; it still has a few issues to
clear up, but the chip temperature and vacuum appear good.
APOLLO had an electronics problem that there wasn't time to fix, so had
to cede its time.
