Shift Summary - Evening
TITLE: 07/12 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Lock Aquisition
INCOMING OPERATOR: None
SHIFT SUMMARY: 
Locking was the usual (as it has been) tweaking SRM because it won't follow the loops currently. Ross mde a valiant effort to show me how to damp PI. Unfortunately the screens he left open for me went into "lock" mode after he left. Jenne left about 05:00 which was right about the time that the PI started acting up. The rest is in the log.
LOG:

05:10 Parametric Instability ETMY_PI_OMC_DAMP_MODE1 started to ring up. Nothing I did seemed to improve it

6:43 ITMX joined the dance. i changed the phase to -60deg and this seems to have turned that one back around. And then, not.

6:54 It's abundantly evident that I(we)could use some training on how to deal with this PI monster. I'm feeling a bit distraught at not being able to mitigate it.

06:57 Watching he lock deteriorate. OMC DCPD saturations have begun....

06:58 LockLoss due to PI.
