Problems: 

DECal LEDs would not work evidently after work at the top ring during the day.   Role removed from SISPI to allow images to be taken,   Please fix on Friday.   No flat fields taken for 2012B-9999.

Had trouble wirh Hexapod interlock breaking at the start of the night.   Apparently trim/tweak values causing displacements/tilts outside the accepted parameter range.  After clearing, all OK.
