Problems: 

At ~2350 local the dome became stuck.  One of the motors is mis-aligned.  This will require mechanical support tomorrow to repair.  We are dead for the night.  Lost 2 hours of DES time.

It was possible to make useful observations in the second half following the dome slit in its static position.
