H1 Lockloss, No Observable Culprit So Far
H1 drops lock 24hrs after lockloss during Travis OWL shift last night. Nothing obvious on our wall monitors (Striptools normal, SEIS BLRMS quiet).
HAM6 ISI tripped, and I forgot to untrip the WD, so I paused the ISC_LOCK at DRMI ON POP to get HAM6 ISI back to ISOLATED.
Yesterday we had a lockloss at just before 1am PST local time & tonight we had a locklos just after 1:37amPST local time. Hmmmm...
