H1 Lockloss At 1603utc (Marking Observatory Mode As MICROSEISM)
After the Calibration Observing drop, H1 had a lockloss about 15min later (with ETMy ring up a second before the lockloss).
Taking Observatory Mode to MICROSEISM since it is still close to 1µm/s.
DRMI looked misaligned, so have went to CHECK MICH FRINGES (but then had another lockloss....but DOWN did NOT ramp PSL Power down from 10W....I'm only noting because this also happened yesterday afternoon).
1821utc Back To Observing
This is post-Initial Alignment (with some ALSx minor grief), several DRMI locklosses, and continued high microseism).
