                 ------------- ACTIVITY LOG --------------
          1st Half Observing Specialist: Jack Dembicky
 Turned enclosure fans on and opened louvers at 17:35.
 Telescope was found at checkout to be pointing near Zenith.  I moved the
 telescope down to the horizon and back near zenith twice to prevent the
 primary from starting to oscillate (which can occur when the telescope is
 pointed at the Zenith).
 We had a firewall issue when the observer first logged in and tried
 FTP'ing test images to NMSU.  Craig was on site and quickly fixed the
 problem with no time loss to observations.  Craig will further
 investigate the problem/fix tommorow to see if he can prevent it from
 happening again.
 I opened the enclosure at 19:25.  Turned instrument over to observer at
 19:50.
 Everything ran very smooth again tonight.
          2nd Half Observing Specialist: Russet McMillan
 Second half was very peaceful, with varying cirrus.  The observer
 reported getting the "no flush, check electronics" error on three
 occasions, but that was out of more than 2000 images, so the error
 rate is still quite low.  As usual, the next image was always fine,
 and the only real difficulty was with re-starting a script in the
 middle.
