              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I had some odd jumps when I adjusted focus for TSPEC.  See tcam images 176, 179.  I was focusing while he was observing and it seemed to self correct after the focus tweak both times.
Seeing deteriorated as the night progressed, especially while TSPEC was on.
At changeover to the last program for the night we encountered a problem with the secondary A encoder/actuator.  This was a different problem than the one we experienced two nights ago (when we actuallyhanged ports and the encoder didn't work as commanded) and Russet had a quick fix.  Tonight we were just changing instruments from TSPEC to DIS and it timed out when I went to focus.  I called Russet and she investigated while Dimitry took cals.  Unfortuantely we were not able to fix the secondary problem, it's possibly cold related,  and Bill said they would deal with it in the daytime, so we closed up for the night.
