                 ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky, J.Barentine (checkout)
 John had the instrument checked out and open/cooling by 6PM in
 preperation for the 1st program of the night.  Nancy started the evening
 getting her darks and then observing Venus with Grim.
 At 21:55 we switched over to CorMass and the fun began with a new
 instrument block.  Russet did most of the instrument block and then some
 computer glitches started to show up in the CorMass camera software.
 Around 01:30 we were ready to start taking calibration images with
 CorMass as well as some useful data.  Around 03:30 more software testing
 started and we continued on with more images around 04:30 until the end
 of the night.
 Images can be found in /export/images/cormass/data/20040504
 Images for Walerstien Object #4
 Star DD Serpens
 Star MR Serpens
 Wavelength and sensitivity calibrations (TBD yet)
 High Z QSO
 Seeing was around 0.5 arc sec.
 Reduced Data to come later for these objects.
