SHIFT SUMMARY:
Lockloss @ 2:37 UTC

I'm fairly confident that a strong wind gust may have unlocked us.

5.5 Mag Earthquake from the top of the world: https://earthquake.usgs.gov/earthquakes/eventpage/us6000mzkf/

I'm Having a reall dificult time getting DRMI & PRMI to lock for some reason. very similar to Ryan's Alog:
https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=77906
Touched the beam splitter a nudge in a few directions to try and lock PRMI.

Check mich fringes is also saying the Beam splitter too far misaligned!

This seems like just a bad alignment and may be related to the fact that the Last Initial Alignment, was done during an earthquake.

GRB-Short E484987

Took alignment back to GPS time: 1400035904 ( the tail end of Initial Alignment before the last good long lock stretch.)

Can now certainly rule out bad alignment. Took PRMI-MICH to 2.6 and the PRMI lock lasts a little longer but still ultimately doesnt stay locked.

I'm now trying the PRMI-PRCL at 4 like Ryan suggested. As I too am seeing the PRMI 20 Hz wiggle Ryan was speaking about.

GRB-Short E484996

I tried to Manual ISC lock through PRMI to test diffent settings so see if they would actually lock PRMI for any longer. I cannot keep PRMI Locked for more than 3 seconds.

Trending PRM Slide values I see that pitch is higher by 11ish  and Yaw is higher by 3 ish since the last long lock.
