Thurs DAY Ops Transition

TITLE: 12/04 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
OUTGOING OPERATOR: None
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 3mph Gusts, 1mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.33 μm/s 
QUICK SUMMARY:

H1 has been locked almost 15hrs....but H1 is going DOWN in prep for the HAM7 vent and will be set to IDLE. 

There will be more CDS (have heard Beckhoff) work, but no "proof of life" for H1 after that work will be done. 

Now the focus is on prep to vent with Kim & Nellie commencing shortly with thorough technical cleaning of HAM chambers.  Other possible items on the list for today:
