Decided to do an initial alignment. Relocked IFO at 17:47 (09:47). Ran the A2L script. Had several SDF notifications for both ETMs and ITMs, could not find a SUS person. Took a snapshot of all and accepted. Set the intent bit to Observing at 18:25 (10:25) After relocking this morning the RF45 noise has come back, at several time per minute rate. This is knocking the range down into the high teens and low 20s Mpc. Confer with Evan, Keita, Mike, Daniel, and Filiberto. Evan & Filiberto going into the LVEA to check cabling. The cabling checks outside the PSL did not change the RF45 glitch rate. Keita & Evan going into the PSL to check for cabling issues there. Lockloss when the PSL environmental controls were switch on. Crew is out of the PSL. Starting to relock.
