                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky
Started cooling (opened louvers/fans on) at 16:30.
DIS has been mounted all day long so Jon could take cals during the day.
He requested that I not home the instrument and he would check the
calibrations since he did not want the turet/slit wheel to be moved.
This
should not be a problem since the instrument was never moved from last
night and he had been taking data during the day.  I did reboot the PC in
the computer room, performed a 'dis init' and 'dis_define_gratings'.  I
don't believe they moved the turet/slit wheel.
Louvers were closed at 17:00 for observer to do cals.
Opened enclosure at 18:00 and turned the instrument for full operations
to the observer at 18:10.
Louvers opened again at 18:35.
Things ran smooth.
 Observing Specialist, 2nd Shift: Noel Camron Hastings
    Started the evening with a focus and all ran smoothly. The seeing was
exceptional around 0.6".
