HTTS saturation notification on Verbal.  Otherwise, everything seemed good at the time of lockloss.

Over the weekend we have had more DAQ-CRC glitches from h1seiex and recently one from h1susex.

There are also IPC errors (see attached MEDM) from the long-range dolphin (X-Arm), suggesting the problem could be originating from the corner station.

Attached plot shows past two days of SUS and SEI IOP CRC counts.

Investigation is continuing.

INCOMING OPERATOR: Travis
SHIFT SUMMARY: in Observe all night
LOG: I attached a plot of violins that are currently over 2 (RMS), and all are OK for this lock, ITMY mode 18 showing a slight increase, all Y axes span around 0.5.

EQ ring-down is over, winds less than 10mph, another few long stretches withouth glitching (~2hours), all 3 IFOs locked.

QUICK SUMMARY: locked in Observe, can see effects of ground motion in ASC, at a level that H1 can easily manage

TITLE: 06/16 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 112Mpc
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY:

Summary is in the previous play-by-play
LOG:

05:24 Switched SEI_CONFIG to Earthquake anticipating a sizable spike from Tonga.

Accepted SDF diffs from the config change

EQ recovery went fairly well. Y Arm was a task.

23:13 ETMX ISI WD and TMSX WD tripped

1:59 reset EX WDs

2:00 RECOVER_EQ engaged (from VERY LARGE EARTHQUAKE) @ .3-.4um/sec on BLRMS

2:05 RECOVER EQ finished - moving to EARTHQUAKE for Initial Alignment (ground movement still high)

2:28 Start Initial Alignment

3:26 SEI_CONF to WINDY

3:35 Time to Re-Lock

3:50 L1 on the Range plot

One-Two Punch from Tonga/New Zealand area - 6.2 / 7.2

STATE of H1: Earthquake
INCOMING OPERATOR: Ed
SHIFT SUMMARY:  Good shift until the last hour when an EQ took us down.  Currently sitting in DOWN waiting for it to ring down.
LOG:

15:16 GRB alert.  TRIGGER_DUR was greater than 1.024 seconds, so am ignoring.  Confirmed this with LLO (Virgo never spoke up).

Lockloss while transitioning SEI to EQ mode for incoming 6.1-6.4 Mag Tonga EQ.  SEI FOMs show a near vertical spike rather than the usual ramping up.

Also, transitioning the SEI mode is still kicking us out of Observe.  Possibly some more SDF work is required by SEI?

Squeezer lost lock.  It relocked itself as usual.
