- 23:11 H1 at NOMINAL_LOW_NOISE
- 0:23 Equipment set-up in CER (Philippe)
- 0:49 Another CER incursion
- 0:30 - 0:32 Kyle's motorcycle
- 0:57 Lockloss (Wind? High useism?)
- Tweaked up ALSy via ETMy
- PRMI was really low, but eventually tweaked up PRM & BS to optimize alignment (DRMI locked fast).
- Moving to around POWER_30W and going slow due to needing dither line convergence. (stayed here for about 14min)
- Paused at LOWNOISE_ASC for about (3min)
- 1:57 NLN
- 0:59 TCS model restart (Danny)
- 1:00 HAM6 shaker install (Robert & Philippe)
- 2:37 Lockloss
- 2:39 Locking. PRMI looked good, so immediately moved on....but LSC signals looked noisy & broke at DARM_to_RF.
- 5:57 H1CALCS had Timing fault. Cleared it via a Diag Reset.
- 5:57 Back to NOMINAL_LOW_NOISE; had discussion; worked on clearing SDFs (attached is a screenshot of the diffs we had before going to OBSERVE).
- 6:15 - 6:56 In this time we toggled between COMMISSIONING & OBSERVING while we addressed the TCS guardian which had a channel changing every few seconds.
- 6:22 OBSERVING (with Danny performing approved TCS
- 6:35 bumped out again! We are trying to figure out if it is Violin Mode Damping or slow control channels for the Squeezer (Georgia took a snap).
- 6:56 OBSERVING and I'm going to slip out while I can!
