                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The night started out clear, with good seeing which degraded to
 moderate as soon the Sloan imager was mounted.  But since moderate
 was still unexpectedly good for the east wind we had, I still
 counted it a plus until it got worse than 1.5 arcsec around 23:00.
 The second half observers noticed a little trouble with the
 lampswitch: an XXX appeared in place of the Neon ON/OFF indicator,
 then resolved itself within a minute.  Later lamp commands worked
 normally, but then I had a failure to close the eyelid for a
 "telmech cov close" command.  Which probably wasn't related, except
 for the way weird other problems seem to congregate right after
 lampswitch failures.  And yes, I do know this is a new lampswitch.
 Second half had thin clouds (which did make life difficult in
 combination with the moon) and moderate to poor seeing.  Everything
 worked well despite a very creditable attempt to crash the DIS
 slitviewer by the remote observer.  The software is noticeable more
 robust than it was six months ago.
 I rounded off the night with a major APOLLO milestone: four
 reflectors in one night!
