Morning Status of the SEIs

Sheila found the two TM ISIs tripped--Looks like a big event hitting the microseisem plus we are having a bit of a wind event.  Sheila was unable to get the ETMx to go up but she was using the 750mHz blends and that may just not work for Lvl3.  We likely need to tailor some blends to work with Lvl3 that don't use the T240s.  I was able to get the ETMx ISI Stage1 up directly to Lvl3 with TCrappy blends as the Bias Position were not far from the targets.  And Stage2 is still using Lvl2 controller with TCrappy blends.

Sheila had no issues getting ITMx back up.  This ISI had been on since Friday 0816utc--not bad.

All HEPIs are operational and running position loops.

The ITMY & BS Appear to be in the same state as I left them last night.  According to the WD last trip time these last tripped about 10:30 & 11:30 yesterday am.  They weren't up during all that time though as we were ignoring them.

As far as the trips on the TM ISIs, there were some significant EQs around the globe in the hour before the trip( such as a 6.9 ~50 minutes before in China), we had elevated winds (no wind monitor at Ends) and running these very aggressive controllers all may have combined to causes these near simultanios trips (8 seconds apart.)

In case you didn't catch it -- the large event was most likely the 6.9 Mag Earthquake in China that Aidan noticed. It took down LLO's seismic platforms too!

We *really* need to get legible ground motion plots posted on the control room walls that remain functional for more than a few hours and are in physical units. This would have been obvious in the S5/S6 era control room.

These plots are on the walls at LLO at present.  We are still working on getting snapshots posted to the web site for off-site inspection.
