                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky
 Opened enclosure at 17:05 for cooling under clear skies.  I switched the
DIS gratings from L - H tonight and did the calibrations.  The red seemed
to go with no problem but the blue test spectra I had a little problem
making IRAF display the spectra (lots of noise when taken with AR lamp, I
increased the exposure to 50sec to try for a better S/N, but that didn't
help much).  The lines were dim on the spectra (but easily visible to the
eye) so I just used my own judgment to determine the correct line
position/wavelength.  I'll have Camron double check the blue just in case
I messed it up since this is my first solo grating change (2nd half will
be using them at 00:10). Russet mentioned I may have a problem with blue
high. Some thin cirrus from 19:00 - 22:00 but nothing to stop observing
for.  Paula checked them before she started observing tonight to make
sure they were correct.
 Observing Specialist, 2nd Shift: Noel Camron Hastings
   I showed up late due to one of my EMT class final exams. Got here in
time to focus DIS for UW program. Everything was working smoothly and no
problem encountered. Paula felt that the DIS gratings were accurate
required no further adjustment.
   I did notice that most of our slit images throughout the night did not
show round images, but images with a slight 'L' shape. I checked the load
sensors on the PMSS and all axis info, but could not find an obvious
culprit. It did not seriously affect our spectroscopy and we still
obtained sub-arcsecond images throughout much of the night. There was
very light, wispy cirrus through much of the night that barely shows up
on the IRSC.
