Lockloss @ 20:20 UTC after 1:15 locked - link to lockloss tool
Sadly a lockloss shortly after a triumphant return to observing. Nothing ringing up that I can see, environment is generally calm except for the consistently elevated microseism, and the lockloss felt quick, so no obvious cause here.
Back to observing at 21:49 UTC. Ran an initial alignment then lock acquisition went fully automatically. No sign of bounce modes, roll modes, or ASC ringups at any point.
