STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY:
IFO is LOCKING at CARM_OFFSET_REDUCTION
Shift was dominated by microseism (hovering at 1 um/s) with a 6.4 magnitude EQ sprinkled in. H1 couldn't lock for the majority of the shift, managed to get there for 1hr and 9 mins before a lockloss.
Lockloss assumed to be due to the environment - lockloss alog 81820
Other than that, there were 2 SDF diffs that were erroneously accepted, then manually reverted by Sheila and I. We then accepted those. SDF screenshot included. The relevant SDFs are the two top ones (dated 21:18)
