                 ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
We started the night working on a problem with the DIS mask (slitwheel)
motor that needed a dark dome. Around 9pm,  Russell and I worked on the new
echelle/dis focus scripts. We spent a few hours finding minor bugs and
Russell fixing them in real time. Next Russet and I worked on collimation
and collecting SH data for adjusting Sag Coefficients. When we finished
with the SH, the folks working on DIS had fixed the mask motor problem and
had a rough focus and collimation of the blue camera on DIS. Unfortunately
the problems with the red camera could not be fixed resulting in  the
camera being shutdown and set to warm. The chip will be removed tomorrow
and either returned to the old chip or the second new chip, TBD.
For the remainder of the night I did a large pointing model. Hopes of
getting throughput measurements on the blue prism were squashed when
I went to mount DIS and realized that the slitviewer was not reinstalled
tonight after the front end of the instrument was taken apart for the
maskwheel motor replacement.
