we had a very brief power glitch at 20:09 UTC (13:09 PDT). It is visible on MAINS_MON trends of all 3 phases in the corner station, and also seen at the end stations (plots attached). Both GC and CDS UPS system reported the event, and the CUR fire panel beeped for about 10 seconds. Many people saw their room lights flicker.

We cannot see any issues with CDS computing, looks like we rode through OK. Jim and I checked the TCS chillers on the MR-mezanine, no problems.
