                ------------- ACTIVITY LOG --------------
Observing Specialist, 1st Shift: Noel Camron Hastings
    I opened at 20:25 MDT to begin cooling. Tested all instruments, all
checked OK. Began Shack-Hartmann testing in place of the time UW10 would
have used for SPIcam. SPIcam is down at the moment and warm. The S-H
testing went well with decent seeing. I took a full altitude sweep, as
well as fan on/off testing. All S-H images above about 82 degrees showed
image motion, recorded on VCR from approximate time marks 2h20m-2h32m.
Tracking was poor as well at this altitude. Could some of the image
motion be due to the azimuth motors ramped up so high. We had seen some
motor noise in PMSS data before, and during this period on the PMSS load
cells, primarily B, there is a strong sinusoidal signal. I did not try a
FFT on it while running for fear of crashing the logging program.
    Switched over to UW10 without any troubles. After Kevin started
running his scripts the GRIM application quit.  I restarted and all
went well.
Observing Specialist, 2nd Shift: Russet McMillan
Second half remained clear with good seeing -- our first completely
clear night since before the shutdown!
GRIM displayed one of each of its favorite bugs during second half.
We saw one "no flush" error that interrupted a scipt, one failure of
the application on the Mac, and one less-familiar problem: around
00:15, the ICC spontaneously lost its connection with the MC, with no
errors apparent in any of the control windows.  Restarting the ICC
opened the connection again.
Aside from the trouble with the GRIM software, everything worked
well.  The telescope pointing, which had been questioned during first
half, was excellent during second half.
