We have had a timing at EY, which in turn caused a Dolphin glitch stopping the SUS, SEI and ISC models.

Dmesg on all three machines shows ADC timeouts. All IO Chassis are visible, so it looks like we just need to restart all the models.

After 49+hrs of lock, H1 went DOWN with what appears to be an issue at EY (see frontends noted in Title & screenshot of Ops & CDS overview).

• ISI Stage 1 & 2 both tripped (leaving as is)
• Originally took OBSERVATORY MODE to Locking, but have since taken it to CORRECTIVE MAINTENANCE.
• After looking through alogs briefly, I then called Dave & he is currently logging into to diagnose.
• Leaving ISC_LOCK in the READY state.
• Awaiting his action for the issue.

Over 47.5 hrs of lock for H1, and with a quiet night which keeps getting quiet as the winds die down.

Corey pointed out that the squeezer manager is giving a warning about the green power stabilization being railed.  Over the last week Daniel and I have bumped up the green power (using the half wave plate) a couple of times, so that we are now using 24.3mW of power into the green fiber.

The transmitted power through the OPO is servo'd, so the launched power is increased to compensate.  The OPO reflected power has also been increasing, which would suggest that the mode matching or alignment into the OPO has increased, or that the losses are changed. 

For now the operators can ignore the message about the green power stabilization, we may want to lower the green power setting for the OPO for the next week.  Daniel is planning to look at a mode scan of the OPO on Tuesday to see if there is evidence that the mode matching or alignment has degraded.

We have been trying to follow and analyze the CARM_TO_TR locklosses. In the last week or two there have been at least 8-10 locklosses attributed to this. Based on the list of channels created by Sheila for diagnostics, I am posting the last 6 CARM_TO_TR locklosses. Looking at the channel (QPDs at the end of both the arms, sums of which are used for monitoring the arm powers) H1:ASC-X_TR_B-NSUM_OUT_DQ, its ringing up with frequencies ranging from 60-100Hz. I will have a look at it during different stretches of lock.

The time zone is local. The down arrow opens up a calendar. Links to the Python script at /opt/rtcds/userapps/release/sus/h1/scripts/restore_suspensions.py. Uses nds. Screenshot attached.

0:18 Observing.  PEM crew noted that they heard several "whoomp" noises while in the LVEA.  They are speculating that it is possibly due to wind, although wind was low at the time.

5:46 Transitioned to EQ mode.

6:47 Back to WINDY mode.

As part of the point absorber paper, I've been looking extremely closely at the ITMY point absorber distribution. Since the heat from the points tends to diffuse into the bulk over time, taking a measurement over a very short time scale yields a much more distinct view of the individual point absorbers. By looking approximately 120s after a power-up, I was able to isolate at least 6 distinct point absorbers on ITMY.

I've centered the HWS coordinate system on the biggest point.

The distribution is such that after 20 minutes, the individual points are much less distinct.
