                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
    I opened at 16:30 MST to begin cooling. All instruments tested OK. I
manually filled the Echelle CCD reservoir and all temps are good. Bob
Lowenstein built a new Remark version that Don York tested. I tried to
download it for testing but the U.Chicago server would not let me, so I
will try working on it tomorrow. All ran smoothly.
 Observing Specialist, 2nd Shift: Jack Dembicky
2nd half observers decided that they wanted SPIcam instead of GRIM tonight
due to clouds.  Mounted instrument for them and checked it out at 00:05.
Clouds for all of the night but the observers observed thru them most of
the night (stopped twice due to weather).
The Echelle ran out of LN2 tonight at 05:05, I did the manual fill of the
instrument then since the temp sensor is out of commision for the time
being (PR has been submitted previously).  Only the camera was filled at
this time (per Camron's instructions) and not the shield (which as I
understand it is filling correctly).  I did not fill it again at the end
of the night since only 1 hr had past since the last fill.
All ran smoothly otherwise.
