                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 Very nice night. Photometric with good seeing all night, a rare night
 of engineering.
 The work on the rotator motor was not completed today so it was left
 powered down. Being unable to do a pointing model at NA2 I used the
 first few hours to work on troubleshooting a TUI script at NA1. While
 the telescope still had not equalized in temperature, I offered a
 few hours to the Triplespec group. Although we could not use the
 rotator and do an instrument block, I was able create a rough enough
 initial instrument block by hand and forced the telescope to reject
 the NA2 rotator for slews so we could get first light on Triplespec.
 First light on Triplespec! With 2.5 hours we checked: slitviewer focus,
 position of the Lyot stop, and able to get some spectra on a handful
 of science objects to check instrument focus verses slitviewer focus.
 The time was very productive!
 At 01:30 I switched to the Shack Hartman and verified that collimation
 was quite good and had not changed much since the adjustment that I
 did a week and a half ago.
 I then switched to fastcam for the remainder of the night.
 No other problems tonight.
