Ops Owl Shift Summary

TITLE: 08/02 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: TJ
SHIFT SUMMARY:  Rough night.
LOG:

10:08-11:43  Initial alignment issues:  Could not get PRX to lock.  Followed Jenne's troubleshooting document and adjusted RMs to previous alignment.  Inputs to ASC-DC1 and ASC-DC2 were too high after returning to previous values, so tweaked their alignment while watching DC PD SUMs.  Still no luck.  Skipped PRC ALIGN.  Moved on to MICH.  Would not lock MICH BRIGHT.  Gave up on IA altogether since ALSY was the main reason I started IA in the first place.  Attempting full lock.

11:52 PRMI will not lock and looks terrible.  Going to try IA again.

12:08 Incoming 7.0 EQ from Christmas Island. 

12:12 Steered PRM to increase the power on H1:AQSC-POP_A_NSUM_OUTPUT.  This did the trick for PRC ALIGN. 

12:29-14:11 Took IFO to DOWN and SEI CONFIG to LARGE EQ for arrival of Christmas Island EQ

14:11 Back to WINDY.  Trying IA again.

14:40 Starting to troubleshoot SRC ALIGN now.

15:00 Moving through SRC ALIGN now.  Handing off to TJ.
