H1 Down for Earthquakes
Relocking this morning has been near impossible with multiple earthquakes rolling through (4.9 from Tonga, 6.8 from Prince Edward Islands, and now a 6.1 from Soloman Islands as I'm writing this) and wind speeds picking up, so I'm going to leave H1 in DOWN and the observatory in Earthquake operating mode until the ground calms down a bit. Seismic configuration has been in EARTHQUAKE since 15:21 UTC this morning.

Ground motion has calmed down enough; starting initial alignment now.
Never mind, 5.4 off the coast of northern California tripped ITMX, ITMY, and ETMX ISIs. We are now in LARGE_EQ seismic configuration
