Jeff Morgan and Dave Woods tackled the SPICAM shutter this afternoon
and was able to make significant progress.  Assembly will continue
Monday, possibly re-assembled and ready for extensive tests by
the end of the day.
Bernadette Rodgers observed with Dis.  We lost a few minutes at the
beginning as the eyelid on the mirror cover lost it's engagement
with the actuator and dropped shut.  Otherwise, no problems.
Tim Harrison used DIS instead of Spicam for his block.  The net was
incredibly unreliable, sometimes stopping to a complete stop for 10min
or more.  The wind had picked up considerably and this did effect
tracking somewhat, hard to keep the last two objects on the slit.
The last 10min of his time was lost as I closed due to high wind.
I remained closed for the first 1.5hrs of Gene Magnier's time .
The wind continued to have occasional gusts slightly above
35mph.  We observed until 03:55 when Gene had no more useful targets
for DIS (time was initially intended to use Spicam).
OBSERVER COMMENTS:
Bernadette Rodgers
Offsetting along the slit was very fast and trouble-free this evening.
I lost about 10 minutes at the beginning for a pointing correction, but
otherwise the run went very well.  I changed my grating settings to
compensate for deltas between the requested and actual central
wavelengths, but the deltas were different from what was expected.

Gene Magnier
Except for the early problems with the wind, it was a successful night.
We are glad we were able to use the time on short notice since Ted Wyder's
program required Spicam.  Our objects set fairly early so we spent
part of the tme doing cals (especially important as we are using custon
masks instead of the usual long slits)  No particular problems with
DIS or communications.
