H1 called for assistance this morning at 10:13 UTC when the 40 minute initial alignment timer expired; it looks like following the earlier lockloss, H1 was struggling to lock (I suspect due to the very elevated secondary microsiesm, plot attached) and started an initial alignment. It took a while to align the arms in green, which caused IA to take longer than usual. I responded to the call right as the SRC was finishing its alignment (IA finished on its own), but when I selected 'INIT' to clear the alert on H1_MANAGER, this caused H1_MANAGER to jump to the 'RELOCKING' state and requested ISC_LOCK to start initial alignment over again. I didn't realize this until IA was a good way through, so I decided to let it finish (meaning IA was run twice in a row). I imagine one could add a check into H1_MANAGER to not re-request an initial alignment if one is already underway to avoid restarting the alignment process when an alert is acknowledged.

Following the most recent IA, H1 has been relocking smoothly and is currently up to POWER_10W.
