  ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
All kinds of fun things tonight.
We immediately started with bad pointing but were able to find GS01's
targets after executing a pointing correction. When we switched to the
echelle for UW02 we had to do the same process with the echelle pointing
script. The level of pointing varied as we moved across the sky.  UW02
lost about 40min due to trying to adjust the pointing.
At the beginning of JH04's program Russet called for time out and we homed
the M2 and M3 mirrors, zeroed the rotator, and ran a quick pointing model.
 Not surprisingly, things were found to be horribly off, especially in
azimuth.  A detailed PR was sent out. Things were a little better after
the pointing model was applied (as in, the star usually fell in the FOV or
very near the outer edge).
We had to go to very bright stars in order to find out where we were most
of the night and, at one point, a bright star was burned into several ecam
exposures (e0008.fits for an example).
There were some high thin clouds over the course of the night but nothing
to keep us from finding out targets...well, not on that front at least.
When opening, the left door had several soft knocks.  When closing, the
right door had some loud groaning.
As a last fun activity, the night log wouldn't generate so I'm having to
send it out via my email.  Hopefully nothing went wrong...
