                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Az vel scale: was 565, measured 576, changed to 575
 Alt vel scale: was -606, measured -606, no change
 Photometric, good seeing, no real problems (a few cases where the
 DIS slitviewer changed guide stars arbitrarily, which is annoying
 but a known bug).  Started training some on-site observers for
 tomorrow night.
 Triplespectra looked good during checkout; I did not try moving it
 over the floor seams since DIS was mounted all night.
