(* means a trouble report has been issued or appended to)
Observing Specialist: McMillan
Opening was delayed in the evening due to high winds and dust.  We
opened from 21:55 to 22:55 and obtained half an instrument block
before closing again due to high wind gusts.  When we re-opened after
midnight to do the rest of the instrument block, the seeing was
excellent for a brief while and then became very bad.  Out-of-focus
donuts with the Fabry-Perot showed adequate if not perfect
collimation.  Both the guider and the Fabry-Perot were obtaining 2-4
arcsecond seeing throughout most of second half, considerably worse
than measured by DIMM.
We completed the Fabry-Perot instrument block and were able to start
science around 01:30.  A variety of different objects were observed
from several of the Fabry-Perot science programs including UW10, which
was not one of the programs scheduled for tonight (UC06 and DD02).  No
official time swaps had been negotiated, and I'm not sure how the time
should be accounted.  Everyone seemed happy, in any case.
The guider shutter continued to be troublesome, at times exposing as
little as 10% of the area of the chip.  However, by judicious choice
of guide stars right at the center of the chip, we were able to
continue guiding.  * The guider monitor refused to display the most
recent guider images, so it was necessary to monitor the shutter by
checking individual images in IRAF.  The telescope tracking seemed
generally good, despite the high wind gusts and bad seeing.
                            OBSERVER COMMENTS
Palunas:  All in all, fairly efficient for a first night.  If only we
could have kept the 0.9-arcsecond seeing, we would have been ecstatic.
Woodgate: Things went quite smoothly.  It's amazing that the observing
specialist managed to keep the guide star centered and keep guiding
despite the decreasing field of view.  It would be nice to have access
to [Al Dierck's] UW finder chart interface, which assists in finding
well-placed guide stars.
