Thursday Morning Ops report.

TITLE: 08/27 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
OUTGOING OPERATOR: None
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 2mph Gusts, 0mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.24 μm/s 
QUICK SUMMARY:

The temperature excursion that EX VEA was having yesterday due to the clean room being turned on, has calmed down a bit.

Diag Main has a new message that I don't recall seeing before: "SEI_CONF might be stuck."  I recall that Jim wanted to do some HEPI coupling test on the BSC2 last night (tagging SEI). 

Currently both the JAC and the IMC are locked. ALS Y arm is unlocked and ISC_DRMI is down.
