              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear night with good seeing.  Very peaceful, except... the trouble with
the echelle cal mirror got worse, and more than half the time I had to go
upstairs to put the mirror into "Lamps" position by hand.  It did improve
somewhat second half, but I still had to help it along twice.  This
problem cost each program a few minutes.
