H1 called for assistance at 07:13 UTC when ISIs tripped for every QUAD, BS, and HAM8 due to a M7.7 earthquake and M6.4 aftershock out of Myanmar. Lockloss happened earlier at 06:33 UTC because of the S-waves of this quake, I'm assuming. At the worst of the shaking, peakmon was at the highest I can recall seeing it at over 128,000 counts.
H1 will be down for a while. I'll check in after a bit and untrip platforms if the shaking has calmed enough and start locking.
I've untripped all platforms and set up H1_MANAGER for the night. SEI_ENV is still in LARGE_EQ, but H1_MANAGER should wait until the seismic configuration is fully out of any earthquake mode before trying to lock.
H1 again called at 12:41 UTC as it wasn't able to finish an initial alignment. ALS-Y was having trouble staying locked, and I eventually ended up adjusting the BS in yaw to improve transmission as I noticed the ALS beam was clipped on the camera (it's still a bit clipped on the right, but less so now). After that, initial alignment was able to finish without issue, then relocking following that has been going automatically as well. H1 is currently relocking in MOVE_SPOTS.
