Ops Owl Shift Summary

TITLE: 03/21 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 98Mpc
INCOMING OPERATOR: Jim
SHIFT SUMMARY: Trouble in the beginning but Craig and Georgia figured it out. After that I played with the CO2Y power a few steps. I had meant to choose the new mask (in the annular location), but apparently it didn't switch when I requested it and I hadn't noticed. I brought it back to its usual 0.0W before I left, but it will need a bit of time to cool down.
