Been locked and observing for 10 hrs 44 mins. H1IOPASC0 timing is red on the cds overview. Not sure if hitting Diag Reset will drop us out of Observe so I'm leaving it alone for now. Hit the diag reset button and cleared the error without dropping the intent bit.
Lockloss 06:02:15 UTC. I hit the H1IOPASC0 diag reset button 06:01:10 UTC. Earlier I noticed a bunch of ETMY IPC went red and stayed red for less than a minute (1169272562-1169272582 -- that's why I decided to hit the diag reset button to make sure that one is not causing the other). Otherwise nothing's obvious on the FOM that could be the cause of the lockloss.
Back to NLN but the intent bit is waiting on TCS_ITMY_CO2 guardian. I'm investigating why it loses its lock point.
Back to Observe 06:52 UTC
The input power dropped by about half a watt compared to the previous lock.
