              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We had an telescope drive issue that unfortunately took all of the first program, and part of the second programs, time.  We think we have the majority of it resolved, but not sure how things got into the state they did.  Separate e-mail sent to the appropriate persons with all the bloody details.  Luckily Bill was on site tonight to help.
No problem this morning parking the telescope at alt 10 degrees.
