TITLE: 12/18 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Unknown
INCOMING OPERATOR: TJ
SHIFT SUMMARY:
- H1 lockloss during calibration work (probably due to a nearby/fast AK/Canada 5.3 EQ).
- Transitioned SEI_CONF to the WINDY state (kept CPS Diff OFF).
- CDS Overview is all GREEN.
- Handing off shift while H1 is Commissioning time (Shiela for Squeezer).
LOG:
- ~16:30 Tyler working in Hi-Bay.
- 16:35 Sheila noticed PCalX trace on the DARM spectrum on the wall increased (notified Ethan)
- 16:39 SUSAUXB123 on CDS Overview had a RED adc error. Since we were out of Observing, David clicked DIAG RESET.
- Dave also mentioned filter changes (yellow CFC errors on CDS Overview) for:
- SUSETMx (related to TRamp change) ----Sudarsha
- SUSPROC (related to Tramp, but also looks like error in code). Want to know who did this and if we are OK with these changes, because
- 16:47 Chandra out to address RGA on HAM6 End Cap (unplugged/plugged and then left unplugged).
- 17:05 Back to OBSERVING!
- 18:17 Optics Lab work (Vlad will be in/out throughout day),
- 18:25 PSL Chiller check (Camilla)
- 18:42 MX & MY visit (Kyle)
- 19:06 MY trip (Karen)
- 21:00 CALIBRATION begins
- Note: Lock Clock restarted when ISC_LOCK went to NLN_CAL_MEAS (to our surprise after chatting about this with TJ last night). However, we do have Dave's medm Lock Clock on the CDS Overview and this is mainting the lock time (it looks at NLN states or higher).
- 21:08-21:11 SEI_CONF to WINDY
- 21:55 Alaska/Canada 5.3 EQ Alert received (with 4min heads up & clearly in earthquake regime). Waited for Jeff to complete a data point and then....
- 21:57 SEI_CONF to EARTHQUAKE
- 22:01 Lockloss
- Locking Note: In GREEN ARMS, not clear when INCREASE FLASHES makes a 2nd attempt...didn't see it try after almost 30min, so intervended & Jeff & I tweaked up Green Arms.
- 23:25 OBSERVING
- 23:45 COMMISSIONING (~90min) begins (Sheila)
