Ops Eve Shift Summary

TITLE: 07/14 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
SHIFT SUMMARY: H1 remained down again for this whole shift, and we will not be attempting to lock until further discussion can be had on the recent alignment changes. This is planned for Monday morning, which means H1 will not be observing until at least then.

The main activities of the shift were in pursuit of diagnosing the output alignment changes seen in the IFO recently, including my SR3 moves looking for good power spots (alog79103), further diagnosis of abnormal fast shutter behavior from last night (alog79102), and Sheila's comments on this situation being similar to that of the output change in late April (alog79101).
