Ops Owl Assistance
H1 called for assistance at 08:20 UTC as it was struggling to relock. Understandable, as the secondary microseism has been rising today and is now to the point where all STS BLRMS are well into the red. After 90 minutes, I finally got H1 to lock DRMI despite good-looking alignment, but it fell apart as it was checking ASC. I'll keep at it for a while, but if the microseism doesn't improve, I may leave H1 down for the night.

Not having much luck. Had a couple more unsuccessful attempts at DRMI before running an initial alignment, which doesn't seem to be helping much. I've set H1_MANAGER to try relocking again on its own and I'll check back again in abit.
