Still locked, despite some increased wind (putting us at 82 hours). Received an alert for a BBH candidate with LLO (VIRGO down for maintenance) at 07:44 UTC.

LOG:
SEISMON errors
Earlier tonight we got verbal alarms and DIAG_MAIN messages about SEISMON connection errors. These errors cleared themselves after a while. However, when I attempted to use the EQ Response button for what I thought was an incoming EQ, it did not produce a plot. See attached screenshot of error message.
The errors were probably from me attempting to restart seismon remotely. I didn't think I was successful, but it seems I was, maybe it just took a little bit to recover? If the all of the epics variables were still wiped when Travis tried to run the eq response script, I'm not suprised it failed. But, it seems to be working again, now.
While mining for info, and posting here for recording, I stumbled on a note confirming that the ETM16 (the O3 ETMY optic) weighed in at 39,580g (with ears) during install into the suspension, which is consistent with what we measured in the lab prior to ear binding of 39,538g (add 22g per ear, 2 ears and you get 39,582g).
Squeezer lost lock, but relocked itself quickly. Back to Observing.
No more MC1 and MC3 glitches seen since the issues and reboots last Wed.
Trends of BOSEM channels since then are attached.

There is a message reporting SEISMON DEAD on the medm screen.
There is also a DIAG_MAIN message reporting: "SEISMON_EQ: Seismon system not updating"
There are instructions for restarting the seismon code on the wiki:
https://cdswiki.ligo-wa.caltech.edu/wiki/seismon
However, I tried restarting everything on both the seismon vm and h1fescript0 (only the epics ioc on screen 1690, checking that I didn't touch anything else, I hope) and the seismon screen is now blank, so I'm not sure what's up. Can't do much more remotely, but I think probably need to completely restart. Good thing tomorrow is maintenance.

Have remained locked and in observing since damping ITMX mode 8 this morning.
No SUS charge sign flip this week Will remain in laser hazard to allow troubleshooting of the GigE cameras, then transition to laser safe for vacuum team to take roamer arm measurements of H2 HAM chambers. SUS charge measurements, IM transfer functions, balun work and possibly Beckhoff troubleshooting will be deferred unless the IFO loses lock.

STATE of H1: Observing at 111Mpc
OUTGOING OPERATOR: Niko
CURRENT ENVIRONMENT:
Wind: 7mph Gusts, 5mph 5min avg
Primary useism: 0.03 μm/s
Secondary useism: 0.16 μm/s
QUICK SUMMARY:
ITMX mode 8 was above 4. Since LLO was down I took the opportunity to take us out of observing to set its damping gain back to 10. We are back to observing and the mode is quickly damping now.

Still locked, wind has decreased and our range is somewhere around 111 Mpc. VIRGO relocked about 3 hours ago, and LLO has been locked for the last 17 hours, so we are in a triple-coincidence state.
