A few changes in hrec structures seems occurred after the break:
- a structure peaked at 261 Hz appeared, and maybe also a small one at 381 Hz
- the structure at 310 Hz moved slightly down, now it is at about 307 Hz.
A structure at ~307 Hz was excited during SDB1 shakings and magnetic injections near SDB1: https://logbook.virgo-gw.eu/virgo/?r=63002.
