Problems: 

Aty 4:44 UT we moved to a standard field.  Somehow the dome tracking switch was turned off.  Although visuallly the switch was showing as off, there was no message in the TCS. SISPI reported a Occlusion warning, without a beep, but kept observing for the seven filters (YzriguN662). We didnt notice it until the first image of the second half observers program was underway.
