Observer Support:

Night Assistant:

Also Present:

Problems: 

Last ten minutes before we handed over the telescope to the second-half observers, when I changed the propID to the new users, I made a typo, and the system broke an interlock. After that, SISPI lost contact with the shutter, and we were unable to recover the system. 

At the present time, first-half -- second-half hand-over, the mountain crew are trying to fix the problem.

Problem fixed at 05:37 UT.
