• 31-12-19 17:02 Porta-Potty person,his estimate was for an hour to hour  to 1.5 hours max. 
  • I was still working on getting both arms to lock in green, so I let him in, and his work did not interfere with locking
• 31-12-19 18:11 18:11 UTC starting initial alignment
• 31-12-19 18:25 changed SEI config to useism_windy and Y arm locked, BRSY is rung up, changed it back to WINDY a few minutes later
• 31-12-19 18:42 started Initial Alignment
• 31-12-19 19:12 misalgined SRM to center SR2, needed 6urad in pitch
• 31-12-19 119:42 done with initial alignment though not complete moving on to locking whole IFO
  • MICH bright, SRY, and SQZ never locked, but aligned SRM and SR2, and went on to full locking

Winds are between 5mph and 40mph, and have been between 5mph and 35mph for the last 4 hours (16:00-20:00 UTC).

INCOMING OPERATOR: Cheryl
SHIFT SUMMARY:

Still recovering from Corner station crash

Cheryl is in early to help with recovery

• IMC recovered
• Various sus guardians needed to be reinitialized as they were still reporting tripped states
• handing off the fun to Cheryl

LOG:

All time in UTC:

There seems to have been a corner station system wide crash. H1 had been locked for 34:08

• 12:07 Dave Barker returned the call for assistance (12:06)
  • seems to be a dolphin network crash
• 12:12 I manually brought IMC and ISC_LOCK to Pause/offline or some state that would keep things from moving/hunting around
  • not sure if anything was actually happening

More news as it happens.....

Most corner station models have crashed, I'm capturing logs before starting a recovery.

SHIFT SUMMARY:  Locked 6hours. Porcupine has been wandering around the car park again tonight!
LOG: On next lockloss, operators should notify John Zweizig by email so the Calibration pipeline can be restarted.

• 00:27 Lockloss. No obvious reason, microseism still elevated.
• 00:32 SEI_CONF from USEISM to WINDY
• 00:51 Jeff B leaving the site
• 01:12 SEI_CONF from WINDY to USEISM
  • changed SEI_CONF back because we had lots of saturations during lock acquisition at states ENGAGE_ASC_FOR_FULL_IFO (normal) and MOVE_SPOTS (less normal). Less saturations relocking in USEISM state.
• 01:48 NLN and Observing!
  • No operator intervention
• 05:33 SEI_CONF from USEISM to WINDY
• 05:45 Heard airplane from CR

No obvious reason, microseism still elevated.
