TITLE: 06/14 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
SHIFT SUMMARY:
More observing than last night, but there was another shorter wind storm (winds over 30mph) which prevented locking for 3+hrs. Commissioing time was used for a Robert measurement and PRCL OLG. Squeezer knocked H1 out of Observing for about 3min toward the end of the shift, but came back on its own.
LOG:
- H1 was on its way back to NLN at shift transition.
- 2318-2352 Pcal Lab (Tony & student)
- 2321-2326 Grabbing laptop in Cleaning Room (near CER) (Robert)
- LOCK#1 (handoff from Camilla): 2317 At NOMINAL_LOW_NOISE, but had a couple stragglers which held up OBSERVING a couple minutes.
- Had some SDF Diffs for ASC/ADS Lines a couple minutes after NLN---they went away on their own
- 2321 VIOLIN DAMPING guardian finished a final 5-min sleep
- 2322 Back to OBSERVING!
- 2351 LOCKLOSS!!
- Lockloss 1370821883: There were some winds above the 20mph for the Corner Station.
- 2352 ETMY x-sensor correction made (jim, see his alog)
- LOCK#2: For this one, it made it to NLN, but waited a 5-min for VIOLIN_DAMPING, and this time the CAMERA_SERVO node was the longer straggler
- 0042 NOMINAL LOW NOISE
- 0048 CAMERA SERVO node was completed and now officially at NLN
-
- 0018 Checking Corner Station DustMon pump (Tony)
- 0048-0121 COMMISSIONING time
- 0048-0049 PRCL olg meas #1
- 0049-0119 Robert Measurements
- 0119-0120 PRCL olg meas #2
- 0115 Start to see wind speeds begin to peak above 30mph :(
- 0121-0219 OBSERVING
- 0219 LOCKLOSS (1370830764.658203): EY has been having winds hitting the 30+ mph range.
- 0252 Observatory Mode to WIND & waiting out wind
- 0410 Return to locking after signs of winds stabilizing/dropping
- 0439-0458 Initial Alignment (since I couldn't touch up PRMI better and Check Mich Fringes didn't help)
- LOCK#3 0511-061
- 0600 pseudo NLN, but had to wait for the Camera Servo to complete after about 13min.
- 0612 OBSERVING (after riding out winds peaking in the mainly 30-40mph range which prevented locking for a solid 3+hrs.
- 0609 PIMode31 verbal twice, but it was damped fairly quickly--no action taken
- 0643-0645 Bumped OUT of OBSERVING due to Squeezer
- 06:43:47 SQZ MANAGER log said: "[FREQ_DEP_SQZ.run] Unstalling SQZ_OPO_LR"
- Going to the OPO_LR node, the log's first line was: "2023-06-15_06:43:46.953215Z SQZ_OPO_LR [LOCKED_CLF_DUAL.run] OPO servo output railing"
- And then SQZ nodes were all actively doing things and returned to normal at 06:45:43.
Tagging SUS. At the first 23:21UTC lock acquisition, the last guardian to arrive and allow us into Observing was VIOLIN_DAMPING. Can we think about reducing it's sleep timer?
