                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 The engineering crew working on the new rotator motor and on interfacing
 Triplespec communications between the ICC and intermediate level did not
 turn the telescope over to me until after midnight. Then there was
 some minor issues that had to be resolved before I could actually
 run the rotator with Triplespec mounted to it. These took about an
 additional hour of Fritz's time.
 I was able to take a pointing model, which I implemented even though
 it could have been much less error had there been time for an AZ axis
 remap this afternoon.
 I exercised the rotator a bit when I did the instrument block for
 Triplespec but there was not enough time to perform all the tracking
 tests of the rotator that was on the engineering schedule. Hopefully
 some time during the day can be used for some of these tracking tests.
 With just an hour of time left in the night I let the Triplespec
 group collect some commisioning data.
 Seeing was moderate to good even though we had variable cloud cover
 all of second half.
 No other problems tonight.
