Had to restart the EY laser.

Looking at the EY SUS alignment it seems to have more or less recovered from the vent. The green return beam still hits the WFS, even so it somewhat high. Using bias sliders of 93.4/-50 for pitch and yaw for ETMY (75.6/-60.5 old) and 144.2/5.8 (no change) for TMSY steers the beam back onto the center of WFS_A.

The EX SUS alignment did not recover. I did not find the return beam. I only searched around the nominal good alignment, so. Trying to steer back by looking at the plots of SUS bias and oplev positions doesn't help. The EX VEA decided to increase its ambient temperature by 1°C.

Probably from the power glitch, the DAQ EPICS shows garbage data for iscey. EPICS readbacks are fine.
