H1 had a lockloss about 90min ago for no obvious reasons. All was quiet as well. Attempted to relock but DRMI did not look great; also went for Check MICH Fringes + PRMI---could not even get PRMI locks after letting it try for 20min. Ultimately went for an alignment and where we are. Flashes look mostly decent and POP18/90 are flashing close to 200, but just have not had any locks (only a few short ~1sec locks thus far). Microseism is just under the 95th percentile. Currently at 20min of DRMI locking.
After over 3hrs, H1 finally locked an "xRMI"!! It took lots of waiting, 2-alignments, and me leaving the Control Room (with Lockloss Alerts on my phone) and working on the JAC table to stop me looking at DRMI and H1 trying/struggling....and just let them do their thing! (was about ready to make some phone calls! Oh and we are currently in USEISM state.
