H1 lost lock at around 9:30 UTC from a M6.5 earthquake from Japan and has been trying to relock since. Due to the continued very high microseism, it has not been very successful (the highest ISC_LOCK state reached being DRMI_TO_POP). Since the continued locking attempts seem to be ringing up violin modes as seen yesterday, I'm going to leave H1 at READY for now until the ground motion calms or the daytime operator wants to make an attempt at lock acquisition.
