OPS Eve Shift Summary

TITLE: 12/07 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 70.7388Mpc
INCOMING OPERATOR: TJ
SHIFT SUMMARY:  Pretty smooth shift as far as locking goes.  Some excitement regarding CP4 (see aLog 32283).  Also, set some arbitrarily high thresholds for most dust monitors to stop alarms.  JeffB will reset them tomorrow.  Locked for over 6 hours now.
LOG:

3:35 CP4 alarm

5:24 GRB alert, contacted LLO who verified that they received the alert, begin standdown

6:24 GRB standdown end

7:10 PI mode 27 ringing up, changed phase from 20 to 120.  Did not go out of Observe.  Are we supposed to go out of Observing to make PI mode changes??

As of now, you do not need to drop out to change either PI phase or gain. We unmonitored these so they wont drop you out anyway. If PI ever gets so high that it takes more than a phase flip, gain flip, or couple thousand gain increase, you're seeing it in DARM, and you're worried about losing lock, you 'd want to drop out.
