The FPMI was generally stable and lock state was sustained for 7 hours.
Inspiral range was about 7kpc.
JST 14:57 the Gr transY decreased by factor 2 (about 0.8 to 0.4) probably due to the SR3 PIT jumped about -25 to -21 (figure). Lock loss didn't occurr at this time.
JST 16:01 Lockloss.
JST 16:02 FPMI recovered automatically.
In the next unlock, it is better to fix the alignment of PR3 Pitch to the previous value.
As far as I checked the history, the SR3 jump is corresponding to the coil actuation. It seems due to the ADS.
We think the suspension itself is healthy.\
Actually, the TMSY-GR is now terrible ! almost 0.1-0.2, while TMSY-IR seems to be moderate.
