(* means a trouble report has been issued or appended to)
1st half observing specialist: Camron Hastings
2nd half observing specialist: Karen Gloria
The telescope was closed tonight due to rainy weather.  So far, no
snow.  Tonight's observers took calibration images.  Bernadette
Rodgers took GRIM2 test images with extra bright quartz lamps.  These
lamps will probably replace the current bright quartz lamps.  I've
included her notes below.

                             OBSERVER COMMENTS
UW05 (Rodgers): "GRIM bright quartz lamp test results:
Comparing f/10 H&K images, a 20-sec expose with the new lamps is just less
than a 120sec expose with the existing bright quartz lamp (see first two
stat. groups below), making the new lamps just slightly less than a 6-fold
improvement!  Instrumental profile in the dispersion direction is identical,
showing no color difference at H & K.
Other "New" images are taken for information, but no comparison images were
taken.  At f/5, chip is just saturated at 30 secs, a 10sec image should not be.
Notice 3rd item down: "K Lamp Off images shortly after lamps went off", may
indicate added thermal background in the first images, but it seems to have
completely disappeared before the end of the sequence (compare means w/2hrs
later).
I'll fax some plots down Monday morning.
As for permanent installation: Let's do it, please!"
