After HEPI work earlier, BS was restored using oplev.

POP beam yet to be found. PRY alignmnent was restored, PRY was locked, but couldn't see anything on MC tube baffle. Thinking that the beam is already clearing the baffle hole, we went to ISCT1 but couldn't find the beam (actually there was some beam but it didn't move when we misalign ITMY). We might have to go 10W before we can find anything.

PRY alignment is dubious. When PRY locks, the beam look low on BS AND ITMY. When we set the beam height on ITMY using ITMY video image, BS beam position came up and looked OK-ish (maybe still low). However, with this new alignment, we couldn't steer ITMY enough to re-establish the PRY cavity as F3 BOSEM output railed.

PRX scanning efforts.  With PRY path aligned (to dubious alignment) and then ITMY misaligned, we scanned ITMX to see if we can see PRX cavity flash, but we weren't successful. We will set PR3 angle such that the beam hits the center of ITMY and scan ITMX tonight.

ITMX oplev is dubious. When we scanned ITMX, OSEMs (M0, L1 and L2) responded nicely but we got nothing from oplev.

ITMX camera should be zoomed out if possible. We cannot see any beam on the ITMX camera, but it's mostly looking at ITMX face.
