We got a smattering of alarms in the MCC for power, magnets, and cryo. Seems like the magnet drops were concurrent with some disturbance to voltage at the CUP. While recovering the magnets facilities informed us that they lost several chillers. We also saw service building temps start to rise dramatically so we decided to turn off box supplies. Currently monitoring other temperatures for other systems/buildings.

Called by facilities after some sort of power issue. Turning off box supplies just to be safe, and contacting DC Power for further guidance while chillers are worked on.

Detune angle was hanging out around -8 degrees and reacting significantly to beam trips. Just tried bringing it back to zero to see if that helps. I think it needs the attenuator opened up a wee bit as well. Don't mind the wiggly GMES - 2L20 is an active lock zone.

error was accumulating on B attenuator especially. Took the opportunity to clear it by homing all the attenuators following the QE.

While looking for the cause of the position instabilities, we found MQJ0L04 has a resistance alarm. The voltage is also in alarm and degrading, so we tried swapping the trim card to see if that help, though it seems unlikely this is the cause of our positional problems.

Card swap cleared the voltage alarm. We will continue to monitor.

It looks like a few vertical lock BPMs in the early arcs stopped reporting changes (or reported them strangely) for a minute or two around this time. To my eye the lock corrector pattern doesn't look all that different from usual and it only seems to have happened for that one excursion, so this might be a red herring. Fig 1 shows a couple excursions but only the one in the red box coincides with BPM weirdness (I think).
