Tuesday Maintenance Morning Shift Start!

TITLE: 12/24 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Microseism
OUTGOING OPERATOR: TJ
CURRENT ENVIRONMENT:
    SEI_ENV state: USEISM
    Wind: 5mph Gusts, 3mph 3min avg
    Primary useism: 0.11 μm/s
    Secondary useism: 0.87 μm/s
QUICK SUMMARY:
OWL Op took ISC_LOCK to idle

Since we aren't locked when I arrived here at 7:30, No In-Lock SUS Charge measurments would be running.
 

Lets check that long Tuesday Maintenance List!..... Empty.... I guess no need to check that twice.

The Primary uSeism looks to be falling, perhaps the secondary wll follow, So i've started an Initial_Alignment and I'll give locking a shot now that the wind is gone and the useism is a little lower.  

I do expect to see the Liquid Nitrogen tanks  to be filled at some point in the morning.
