Title: 11/12/2015, Evening Shift 00:00 – 08:00 (16:00 – 00:00) All times in UTC (PT)

Support: Jim W., Nutsinee,
 
Incoming Operator: Cheryl

Shift Summary: Lockloss at 06:03 (22:02) – Probably due to high winds (in the high 20s to mid 30s with gusts over 40mph) and increasing microseism (centered at 0.8um/s with high at plus 1.0um/s). Attempting to relock. 

The wind has dropped a bit, but microseism is increasing. Switched the ETM-X Y and ETM-Y X dof from Quite90 to 45mHz to see if this will help with locking. ETM ISI CPSs are not rung up.  

Relocking seldom making it past LOCKING_ALS and ETM-X ISI CPS starting to ring up. Put the IFO into a DOWN state and reset the ETM X & Y blends back to original settings. ETM-X ISI CPS has settled back down to a normal state. When wind and microseism calm down will work on relocking.
