SHIFT SUMMARY:

Lockloss from SQZrs PSAM activity.  
https://ldas-jobs.ligo-wa.caltech.edu/~lockloss/index.cgi?event=1413215714

Relocking notes:
I had IMC Locking issues before entering into Initial_Alignment.

And then I had IMC Locking Issues in SR2 Alignment as well making Initial_Alignment incredibly difficult to Get into and Complete.
Sheila asked me to just take the IMC to Offline and wait until the PSL glitches.   

Reached Nominal Low Noise at 18:51 UTC

Commissioning activities started with:

• Josh's Osem injections Josh [Elenna requests start with PR3]
  Another Lockloss During Commissioning.

• Contrast defect Elenna [20 minutes]
• 1 hour step PSAMs with ASC on [Vicky, Camilla]
