              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Variable seeing and variable cloudiness.  It was never quite photometric,
but seeing did get very good during second half.  There was a strong smoke
smell around morning twilight, due to a fire in Sonora, Mexico.
I was able to complete most of the engineering tasks, but some work
remains to be done with DIS.  The recent warming and pumping of the
instrument has substantially improved the red side dark current and
"wings" of scattered light, but we're still doing a quantitative
assessment, and of course we will need to continue to watch for
recurrence.
Agile checks out well, but the instrument's "handedness" has changed so
that the default orientation is now north up, east right.  We think this
may have been caused by a firmware update, since otherwise it seems
inexplicable.
