              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
During checkout, I had some trouble with TSpec. See PR. Also, the
instchecks script did not run for TSpec. It attempted to set NFS = 8, and
failed. I had to take darks manually. Has anyone been modifying this
script?
Weather was good, and seeing varied between 1.5 and .85". Productive
night, however, during UW12 program, George reported some pointing
problems. When his target was in the FOV initially, it appeared in the
left-hand side of the slitviewer always. We lost some time to pointing
error when we could not verify if a target was his, and I was forced to
confirm the Echelle's filter wheel position and do a pointing check. The
pointing check was not successful, but when he sent me his coordinates, I
was able to slew and we got his star to appear in the extreme left of the
slitviewer FOV. Not sure what to make of this. The rest of the night was
uneventful.
