SHIFT SUMMARY:
LOG:

• 00:38 and 01:53UTC Verbal reported that IR was not found, apparently incorrectly
• 00:54 SEI_CONF et to USEISM_WINDY after multiple locklosses at LOCKING_ALS. I switched it back to WINDY but didn't log the time
• 01:16 Initial Alignment
  • ALSX wouldn't move past the OFFLOAD so I waited for a good period of alignment and moved to OFFLOAD manually
  • the remainder of Initial Alignment ran accordingly
• 02:32 NLN
  • accepted SDF Diffs due to SEI_DIFF configuration (image below)
• 02:34 H1 back to Observing
• 03:26 GRB LONG E365259
  • ignore - LLO contacted

    SEI_CONF state: WINDY
    Wind: 37mph Gusts, 26mph 5min avg
    Primary useism: 0.11 μm/s
    Secondary useism: 0.62 μm/s
QUICK SUMMARY:

• 00:08 Moved SEI_DIFF to CORNER_DIFF_CPS to see if I can get some better results locking arms.
  • ALSX&Y showing good flashing alignmentfor beginning attempt
• 08:15 there is a Benton County Sheriff's SUV backed into a parking spot next to the LSB by the Electric car charging station.
  • I called Bubba to inquire about this and he had no knowledge as to why.
• There is no observable tumbleweed buildup along Y-arm but there seems to be an apreciable amount accumulating from MX to EX

00:24 Begin re-lock attempt. Fingers crossed.

SHIFT SUMMARY:

Keita called to inform me that we are no longer standing down for a potential supernova and had me set INJ_TRANS back to INJECT_SUCCESS.

Attempted to relock after the lock loss from observing, but without success. Eventually stood down while the wind continues.

LOG:

16:08 UTC Set SEI_CONF to EARTH_QUAKE for magnitude 5.8 earthquake in Armenia
17:14 UTC GRB-Short E365206 Fermi Confirmed with LLO
17:59 UTC Set SEI_CONF back to WINDY
18:15 UTC INJ_TRANS set back to INJECT_SUCCESS per Keita's request
19:00 UTC Lock loss from observing. Likely wind.
19:33 UTC GRB-Short E365213. Not locked, ignoring. Confirmed with LLO.
19:45 UTC Lock loss from LOCKING_ALS.

20:09 UTC Resuming locking
20:22 UTC Lock loss from CARM_TO_TR
20:28 UTC Lock loss from ALIGN_RECYCLING_MIRRORS
20:29 UTC Pausing at READY again
22:06 UTC Set SEI_CONF to MORE_WINDY
22:08 UTC Attempting to lock again
22:10 UTC Buildups in green arms are not stable. Setting SEI_CONF back to WINDY.
22:27 UTC Lock loss from ACQUIRE_PRMI
22:28 UTC Pausing at READY again

Lost lock from observing at 19:00 UTC, possibly from high winds. Struggling to relock.

SHIFT SUMMARY:

I was told by Cheryl that we are keeping INJ_TRANS set to INJECT_KILL for the indefinite future due to the possibility of a supernova.

There was one lock loss from observing.

I ran across a user code error in CHECK_MICH_FRINGES. I think I may have fixed it, but CHECK_MICH_FRINGES did not leave the alignment in a good state for ACQUIRE_PRMI. We lost lock at ACQUIRE_PRMI twice before I ran an initial alignment. The initial alignment seemed to fix the issue.

Currently riding through a series of earthquakes in Chile with SEI_CONF in EARTH_QUAKE mode.

LOG:

20:01 UTC Lock loss
20:29 UTC Lock loss from MOVE_SPOTS
Fixed user code error in CHECK_MICH_FRINGES (alog 55231)
20:58 UTC Lock loss from ACQUIRE_PRMI
21:16 UTC Lock loss from ACQUIRE_PRMI
Starting initial alignment
21:43 UTC Initial alignment done
22:01 UTC Lock loss from ENGAGE_ASC_FOR_FULL_IFO
22:43 UTC Observing. No SDF differences.
23:22 UTC Set SEI_CONF to EARTH_QUAKE for magnitude 6.0 earthquake in Chile

See attached.

Just lost lock.
