SHIFT SUMMARY:
Today there was continued work looking at the lead-up to the CARM TO TR step for ISC LOCK. For the most part DRMI reacquisition was fairly easy (Sheila alog-ed about a random PR3 move which was odd.)
Toward the end of the shift, OM3's heater was increased from 1.0 to 4.0W for over the weekend.
