SHIFT SUMMARY:

Lots of EQs from Taiwan today, only 1 lockloss from them. The range has been lower today, the high frequency squeezing doesn't look as good as usual.

Lock#1

• 21:18 UTC Observinghttps://ldas-jobs.ligo-wa.caltech.edu/~lockloss/index.cgi?event=1397866956
• 00:22 UTC lockloss

Lock#2

3 more EQs from Taiwan (4.5, 5.8, 5.2) came through while I was trying to relock.

Right click on an MEDM window, select Execute -> Search Model.

Then click on a channel.  A browser will pop up showing the design of the model that generates the channel.

Thanks to Takahiro Yamamoto for the code.

You might have to log out and log back in to see it.

We've been locked and observing for 1:40 following the lockloss at 00:22 UTC, range is lower this lock (High frequency SQZing doesn't look the best).

No obvious cause, https://ldas-jobs.ligo-wa.caltech.edu/~lockloss/index.cgi?event=1397866956

SHIFT SUMMARY: Was able to relock this afternoon during a lull in earthquakes from Taiwan just in time for a candidate event to come in. BNS range is on the lower side; Camilla comments that SQZ doesn't seem to be tuned well.

Minutes before noon and before H1 would hit 22hrs, H1 lost lock most likely due to an earthquake(s) (M.6.1 to 6.6) from Taiwan although it's R-Waves are still inbound.  Taiwan has had multiple M5+ earthquakes since 2am (local) this morning!

- HAM5 H3 has a slightly louder-than-normal peak at 60Hz.
- Stages 1&2 Vs for BS, ITMX, ITMY, and ETMX all have a peak around 16 Hz that is usually not there.
Everything else looks normal.

As Jim and others are starting to build up a good MEDM interface and otherwise use the rest of the HAM1 TT L4C feed-forward infrastructure I installed several moons ago (see 63115 and 63300), we've discovered that I overlooked adding useful test points at the summation point of the DC centering DOFS DC1 and DC2. These "FFHAM1_IN" and "FFTRGT_IN" fast test points, and corresponding EPICs readbacks were added to all the other summation points (CHARD, PRC1, REFLWFS_RF9_I, etc.), I just missed it for the DC centering loops.

Attached are screenshots after they're now in place.

We'll install these by recompiling, installing, and restarting the h1asc.mdl front-end model tomorrrow during maintenance.

PMC REFL has been on the rise again for the past 5 days or so, perhaps lining up with a slight increase in the average PMC temp output? Unsure if these are related.

Happy Earth Day!

Nice night for H1 with lock around 18hrs and clean-range just under 160Mpc & double coincidence w/ L1 for most of this lock (Virgo is in a troubleshooting state for most of this time).

Microseism has been turning around since 24hrs ago and is mostly below the 50th percentile.

SHIFT SUMMARY: Quiet night, we've been locked for  just under 10 hours, PSL Anteroom red dust alarm at 23:32 UTC. I've seen MC1, MC3, and PR3s cameras flash blue a few times. The wind started to calm down around 06:00 UTC and microseism continues to decline.

We've been locked for almost 6 hours, the winds picked up and is bleeding into the 0.03 - 0.1 bandwidth. Microseism is decreasing.
