Ops Tuesday Morning report

TITLE: 04/28 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: MAINTENANCE
    Wind: 9mph Gusts, 4mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.12 μm/s 
QUICK SUMMARY:

When I arrived there was an alarm for the Fire Pumps sounding on the verbals machine. Fire Pump 1 was on at 14:28 today possibly because of Work permit 13207.

LVEA temp is climbing and hasn't returned yet. Perhaps this is just the mega cleanroom affecting the temperature, but I will keep an "I" on it.
