Ops EVE Shift End

TITLE: 07/21 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: LVEA is LASER HAZARD. The dust alarms keep going off for the optics lab since there's so much stuff in the air despite the low wind.

Still some confusion regarding MC2's M3 BIOs. I went into the CER and tried turning the BIO chassis for MC2 off and back on (SUS-C1 U17 and U18). Checked plugs to chassis and to BIO cards. Tightened a couple screws but plugs didn't seem to be loose. Don't think tha would've done anything, but we'll keep looking at it tomorrow.
