Between 1383589977 and 1383590038 I adjusted the OMC 3MHz demod phase from 132 degrees to 147 degrees.  The OPO lost lock (PZT at 110V) at around 18:00:39 UTC, the squeezer relocked itself but took a few tries to get the FC handoff to IR.  After that we went back to observing but the squeezing was poor, so I adjusted the SQZ angle in lock.  

I don't understand why the sqz angle should be different after that relock.
