Since Livingston was down, we took the opportunity to tweak the alignment into the reference cavity since its transmission had fallen from ~3.9V to ~2.1V. The alignment was tweaked (see RCAlignment.png). However the noise eater decided to start oscillating. Toggling the switch restored the reference cavity transmission to a higher value (NoiseEater.png). Christina also wiped/mopped the Ante-room and the Laser Room. We confirmed that all the computers were powered down. Christina/Jason/Peter
