OWL Ops Summary

TITLE:  9/24 OWL Shift:  7:00-15:00UTC (00:00-8:00PDT), all times posted in UTC

STATE OF H1:  Unlocked.  Waiting out Earthquake.

SUPPORT:  None (& not needed)

SHIFT SUMMARY:

More action during this shift with the end of the long lock stretch (no obvious reason for lockloss by Jim, although he said he mentioned 45MHz issues for end of that lock).  Went through an alignment & then had a 4hr lock, and then had another Unknown lockloss.  Then while trying to bring back H1 had some issues (noted earlier).  And now handing off unlocked H1 with seismic ringing down from Vancouver EQ.

Shift Activities:

  • ETMy Saturations:  9:14 (set of 3), 10:18, 10:29, 11:19, 11:37, 11:39, 12:18, 
  • 8:34 H1 back to Observation
  • 9:04:15 H1 slipped out of Observation accidentally for 15sec
  • Noticed CDS O1 Overview was not up on video2 (had old version), so I brought it back up.
  • 12:35 Lockloss (nothing seen on seismic, and all H1 striptools show no issues; therefore UNKNOWN)
  • 13:54 Earthquake Verbal Alarm (Vancouver 5.5 quake)
