Transition To DAY

TITLE: 07/14 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Earthquake
OUTGOING OPERATOR: Travis
CURRENT ENVIRONMENT:
    Wind: 4mph Gusts, 2mph 5min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.07 μm/s

Quiet at the moment with small useism & low winds.
QUICK SUMMARY:

Richard and Travis were troubleshooting IMC when I walked in.  Richard asked me to run the DOWN state (Guardian was in the INITIAL_ALIGNMENT state), and this locked up the IMC.  Will start an initial alignment from scratch now.

Note:  OBSERVATORY MODE is in the EARTHQUAKE state.  It was taken to OBSERVING last night.

Initial Alignment/Locking Notes:

INPUT_ALIGN

While running through the Input Align step, noticed big ASC signal ringing down after OFFLOADING (screenshot attached).  I don't recall this happening before & just thought I'd mention it because Travis had his IMC issue during this step of INPUT_ALIGN.

MICH_DARK_LOCKED

The spot here was bright & I wasn't able to get it to the usual dark spot.  I centered this spot & moved on.

Locking Issues:

So after the alignment, couldn't get much action while trying to lock PRMI (looked very quiet), and it also looked very quiet/dead for CHECK_MICH_FRINGES.  So I went to DRMI locking and looked aft flashes and moved the BS accordingly.  Managed to eventually get a lock.  Just wondering if my alignment was bad due to issue with MICH_DARK_LOCKED.
