TITLE: 08/06 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Ed
SHIFT SUMMARY:

Ran Alignment by hand (i.e. bypassing the automated INIT_ALIGN alignment guardian node).

Needed to pitch PRM quite a bit during alignment (and accordinly a bit of pitch with the BS).

Have FM1 (-20dB) still ENABLED for the PRC1_P filter bank.  (This was to allow one to get past DRMI in locking)

Observed broadband noise on DARM.  Andy L noted a possible suspect for this is the Squeezer.
LOG:

• 11:35 OBSERVING (after being down for 7hrs 5min)
• 12:00 Control Room Work Stations rebooted (one of the computers [zotws19] beeps repeatedly, until I power cycle it & then it looks like it booted fine)
• 12:14-12:37 Broadband noise seen on DARM (from 500-3000Hz)---possibly related to the Squeezer.
• 12:50 GRB on Verbal, notified LLO & Virgo.  At 12:56, confirmed it's Trigger DUR was 2.048s, so ignoring & RE-ENABLING injections.
• 13:52 Notified LLO running charge measurement and then will immiedately move on to Maintenance.
• 14:45 PEM Injection started (out of OBSERVING)...might have not been run, so
• 14:53 Ed re-running PEM injection
