Tues EVE Ops Summary
TITLE: 05/29 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Wind
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:
A bit of a wind storm at the beginning of the shift but luckily strongest winds only lasted about an hour and allowed for locking shortly thereafter. Had about 4-5hrs of observing during this shift (with another lockloss minutes before the end of the shift).
LOG:
- 0010 Winds drop below ~30mph!
- 0100 NLN
- 0105 nuc30
- 0113 Took SQZ Manager to FDS
- 0115 Ran SCAN_ALIGNMENT_FDS and then SQZ Angle
- 0140 Naoki joined me in teamspeak to look at alignment (& camilla also joined). ZM4 was adjusted in alignment slightly again.
- H1 range is hovering around 130-140Mpc.
- 0411 LOCKLOSS (
- Locking notes:
- ALSx arm took some time to lock as it had trouble staying locked (but eventually made it)
- PRMI looked off in yaw, and I was not able to get it better by hand. Ran a Manual Alignmnet of just the PRC. Unfortunately, DRMI still had issues locking (even with SRM tweaks, so a full Initial Alignment was run). After this H1 made it to NLN with no problem.
- 0616 Back to Observing with a range around 150Mpc.
- 0752 Sadly as I typed this summary H1 had another lockloss (this was with calm winds)
LATE Squeezer Entry For Yesterday!
Yesterday for the lock at the beginning of the shift (NLN around 100utc after the winds), the Squeezer did not lock on its own and also needed to run the scan_alignment_fds + sqz_angle states; also Naoki tweaked ZM4 a little before H1 eventually went to Observing. Below are the SDF diffs screenshots which were accepted:
