Ops Day Shift Transition

TITLE: 05/02 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
    Wind: 11mph Gusts, 9mph 5min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.10 μm/s
QUICK SUMMARY: Lost lock right before I showed up, ALSX seems to have good power (~1.05) but the WFS will pull it away after they engage. The polarization is around 20%  and cannot be reduced, I'm sure this isn't helping. Aquired PMRI though so we should be okay.

When locking DRMI, I couldn't improve POP18 more than 55 or so. I decided to move on, and there was no dip in this signal even after engaging the ASC, but it broke lock at the DARM_TO_RF state. I'm going to run and initial alignment and see what it looks like after. If this works well, then I've had to run an initial alignment after every lock loss this week...
