              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear skies all night and good seeing for most of it as well.  Everything
worked well with the exception of the echelon slitviewer filter wheel
getting out of position; I repositioned it by hand and it seemed fine
after that.
