                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
aves of thin high clouds passed by tonight, and we had seeing from
subarcsecond to 3 arcseconds at various times, but we were able to
take data the whole night.
Pointing was good at all three instrument ports, although I did take
an opportunity for some extra adjustment at Agile since the
observer's event was late in second half.  We had some difficulty
with the Agile rotator just after changing instruments, so I had to
coax it along -- but once I got it going, it behaved for the
remainder of the night.
During NICFPS testing I managed to induce one failure in many
thousands of images, but this coincided with instrument handling so
it's unclear if this is the same kind of failure we were seeing in
the middle of observations.  More tests with the instrument mounted
on the telescope may be indicated.
