This morning we relocated the ITMy OpLev laser to make room for the ITMy CHETA table, which is going to live in the old laser location to the -Y side of the ITMy OpLev receiver pylon. We moved the laser to the +X side of the beamtube, see attached pictures. Before the move the OpLev SUM counts were ~9500 and after the move they are ~9300, a drop of ~2.1% (so not at all concerning, IMO); pitch and yaw alignment were unchanged. Since we had to open up the cooler to disconnect the fiber for the move the laser will need some time to return to thermal equillibrium; I'll monitor it over the next several hours (SUM counts may return to the pre-move value during this time period). This completes LHO WP 13534.
