STATE of H1: Commissioning
INCOMING OPERATOR: None
SHIFT SUMMARY: H1 was locking fairly well until the commissioners left for their dinner break. Then we were slammed by a series of EQs (6.1 in Nicaragua and 3 aftershocks and 5.9 in Solomon Islands). Since then, things have not been locking so well.
LOG:
3:46 Sensor Correction turned off in anticipation of incoming EQ.
3:57 ITMx and ITMy ISI WD tripped.
4:35 Attempted to start locking again, but could not get past DRMI. Realized this was due to another incoming EQ. Set IFO to DOWN.
5:58 Started Initial Alignment
6:35 Finished IA, back to locking
