Power Outage
In addition to other work that went on during the power outage.  We cleaned the Switchgear cubicles and cycled the breakers in key areas.  The MCC in the Carpenter shop. The MCC that feeds the chillers. This unit looks as if condensation in forming in the bottom a fair amount of rust has formed.  It also had dead mice in the gear.  The main switches in the Mechanical Room.  The MCC in the LSB.  The main panels in the End Stations.  We did not get to the Mid stations as we can do them at anytime and not bother the IFO.

Robert ran some seismic tests in the LVEA.  One problem was the Generator running by the carpenter shop.  Large peak in the data.

We also checked the status of the Emergency lights across the site.  We had a few immediate failures and some that did not last the full 90minutes required.  We will be addressing these issues.  A few actually lasted 3 hours.

Of particular concern were the exit lights in the OSB.  I will get with John to discuss a path forward.
Also the FM200 panel did not survive the outage.  We lost a power board around 8am

All in all the outage went smoothly and the return to normal only had some minor glitches.
