It still looks reasonable.

Before I started touching the BS, only ITMY reflection of SQZ beam was visible in AS camera and nothing in ISCT1 camera.

Betsy found that the ITMX and ITMY reflection of SQZ beam were already almost on top of each other in HAM3.

I moved BS in YAW by negative 51 counts and the differential Michelson alignment was already good, MICH fringe was visible in both of the cameras, therefore BS alignment itself is still reasonable.

On ISCT1 camera, the beam position looked different from what it used to be last Thursday (see today's video of MICH fringes PXL_20260630_202239770TS.mp4 and compare that with alog 90759). Whatever is causing this, it's not BS because BS itself cannot cause common MICH change for SQZ beam that goes to ISCT1.
