Monday Mid Shift Update

TITLE: 05/06 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 151Mpc
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 29mph Gusts, 19mph 5min avg 
    Primary useism: 0.08 μm/s
    Secondary useism: 0.15 μm/s
QUICK SUMMARY:

After a lockloss while holding ISC_LOCK at LOWNOISE_ASC to fix the TRANISTION_FROM_ETMX issue, we shifted focus to fixing the PRCL1 issue we were having with DRMI, so we were holding in DRMI for a bit. Once that was fixed we went back to holding in LOWNOISE_ASC. after that Commissioning was started.

We were able to get back to NOMINAL_LOW_NOISE at 16:50 UTC and got back into OBSERVING after Commissioners were done with their Commish wish list at 18:36 UTC.
H1 has now been Locked for 3 hours.  
Just unlock....

Lockloss 20:00 UTC Most likely to wind gusts.
Lockloss screenshots attached.

While waiting for 50+ MPH winds to blow away, I started an Initial Alignment.
This was going well enough until the SUS SRM watchdogs tripped.
 

H1 is currently sitting IDLE, due to this wind.
