TITLE: 07/26 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: LOCKING (ETM violin modes have been an issue)
INCOMING OPERATOR: Jim
SHIFT SUMMARY:

After mysterious lockloss, H1 needed an alignment (due to misaligned PRMI) & then violin modes took up the last few hours of the shift.  Locklosses while in DC READOUT (& earlier steps) made it frustrating to work on damping these pesky modes. 
LOG:

• 11:06 LOCKLOSS:  PRMI misaligned & then violin modes have been issue
  • Although EQs incoming, did not appear to be seismic & no other obvious reasons seen.
  • Ran Initial Alignment & was straight forward
  • Violin Mode damping
  • This is still ongoing.
• 13:41 Contamination Control inventory work in the Cleaning Area (Jeff B.)
