Shift Details:
Support: Sheila 
Shift Summary: IFO unlocked. 

After a difficult but successful Initial Alignment by the Evening shift, working on relocking. After a long night (very long for Sheila) of many tweaks were able to get the IFO to lock at DC_READOUT once for about 30 minutes. After this lock broke we were unable to get past green locking. There are problems with INPUT_ALIGN hanging at LOCKING_XARM_IR, (see aLOG #30881). Sheila did not think there was much chance of successful locking. I put the IFO into DOWN to await the refreshed minds and fingers of the day shift to continue the good works of the past two shifts.
