TITLE: Ops Day Summary: 15:00-23:00UTC, 8:00-16:00PT, all times in UTC
STATE of H1: major interference in locking the from earthquake after effects, useism, and wind - locking is getting progressively better
Support: Jenne, Evan, and Sheila
Quick Summary: IFO is locking well up to DRMI, and gotten past DRMI, but not to ENGAGE_ASC, can now get to DARM_WFS
Details:
- Ground motion significantly effecting arms, with arm powers in green and red dipping down to as low as 0.5-0.7
- Stopping at DARM_WFS to damp ROLL mode early - this is the stage where the signal becomes useful
- Switched to Quiet_90 ISI blend filters - alogged earlier
- Needed higher gain to lock X arm in IR, while doing an initial alignment
- Day spent considering and sometimes trying new approaches to improve locking with high ground motion
Shift Activities: work around the site
- Joe and Chris on X arm sealing the beam tube, morning and afternoon
- Richard to Electronics Room, 20:45-21:15UTC
- Kyle on Y arm at the y28, doors closest to End Station
Control Room Display:
- restarted cameras on video4 (camera's froze)
- restarted nuc4's dtt, DRMI_FOM_displacements
- Carlos working on nuc5 (couldn't get to lower screen when logged in)
Currently:
- locking is getting progressively better
- earthquake (~14 hours ago) effects are gone
- useism is slowly coming down
- wind is dying down
