PI mode 23 has rung up a couple of times coincident with a glitch in DARM. It is not immediately obvious which precedes which. There is no gain set for damping this mode and it has come back down on its own.

From the camera the tumble weed bailing now appears close to the corner station on the X arm.

Have remained in observing since the start of the shift. No observed jumps in the PSL enclosure temperature.
