              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
High dust and winds kept us closed at the beginning of the night. Open,
but cloudy at 21:15. Remained open. We were never able to get on sky with
PU01- it was too cloudy to guide on her faint targets, so it was lost to
weather. She gave up a bit early, and let PU05 take over.
During the Echelle runs, PU05 and UW12 noticed that the stars they slewed
to we almost invariably in the lower right-hand corner. At one point, the
star did not appear fully in the slit-viewer, and I had to manually nudge
the telescope to be able to center-select the star. I did a successful
pointing check, but was unable to investigate further. For the time being,
we opted to cope to avoid losing sky time.
Once the weather cleared up, the night was pretty productive. No more
problems.
