              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Sprinkles in the middle of the night, but we were able to be open for a
few exposures in the evening and a more substantial period in the
morning.  The second time we opened, the slitviewer computer crashed and
needed a power cycle during focusing, which cost a few minutes of time.
Later there was one case where the slitviewer stopped taking images, but
that time I was able to recover just by repeatedly trying exposures until
one succeeded, with essentially no time lost.
