Did not see anything obvious on signals. And can't make out anything obvious from a glance at the Online Lockloss.
During the last lock, DIAG_MAIN said polarization for ALSy was high (it was hovering around 30 and up to 41), so I went to READY state on ISC_LOCK and did a remote adjustment of the polarization. It's a bit scary because when restoring, polarization went all the way up to 170%! But able to bring it down fairly easily (first with stepsize of 5). One thing I neglected to check was ALSx, because when I was done with ALSy, ALSx was now high! I was able to bring it down only to 17.
For locking, had one lockloss around the DRMI_TO_POP step. 2nd attempt had a short DRMI lock of seconds...currently waiting for PRMI. May try an Initial Alignment if no luck in the next few mintues.
NOTE: Just locked PRMI. Used BS mainly to adjust mostly PITCH and a little Yaw. Moving back on to locking!
NOTES:
1) Online Lockloss Tool & PEM channels?: Are there any PEM (i.e. seismic) channels that it looks at? SEISMON noted some EQs (but they didn't show up on the nuc5).
2) NDScope & Trend data: For the ALSy Polarization, I wanted to get a trend of the last couple of days, but it would only go about 1-day back. Is this normal? I went ahead and used Dataviewer to get the trends.
I don't seem to have a problem using ndscope to trend ALSY polarization. Not sure what was going on...
