Owl Mid-Shift Update

Much of the first half of the shift involved waiting for the earth to stop ringing due to the Alaska earthquake

Did my darnedest to avoid an Initial Alignment, but ISC_LOCK pretty much forced me to.  INITIAL ALIGNMENT successful for every step except for SRC ALIGN (I later aligned SR2 & SRM by hand, but SRC ALIGN was still NOT HAPPY & FAILED, so I skipped it and ended the INITIAL ALIGNMENT.).

[SEI_ENV finally went to calm at 1050utc (350amPT)---almost 4hrs later!]

After Alignnment, DRMI locked immediately when prompted!  Now continuing through ISC LOCK.

OK, H1 made it all the way up to OMC Whitening without any issues.  Now just waiting for violins.  I've taken all of the non-nominal modes to their nominal gains.  The wait continues....and now I go make lunch.

After 5.5hrs, H1 is back to OBSERVING post big AK EQ.

(Violins damped down in about 40min....I thought they were taking longer---I could have taken us back to Observing 6min sooner, but I was finishing making lunch. (L1 is powering up now)
