Quick Summary: Locked and Observing 22 hours
Locked 18h. Over the last few hours we've had our range drop to 110Mpc as the wind has increased to 35mph (see range vs wind plot). I have checked SQZ channels as descried in alog 54967, all are fine.

INCOMING OPERATOR: Patrick
SHIFT SUMMARY: Had issues locking due to high microseism and wind, also had to go to MICH_DARK_LOCKED to get the BS aligned properly. Wind and microseism have declined since the start of the shift. In Observing 6 hours.
LOG:
00:18 (16:18) Robert back from EY
00:34 (16:34) Trying MICROSEISM_WINDY seismic configuration
00:57 (16:57) Took IFO back to INITIAL ALIGNMENT to run MICH_DARK_LOCKED. This seems to have worked better than MICH_BRIGHT in this case
01:46 (17:46) At NLN, going into Observing. No SDF diffs
04:31 (20:31) Returning to WINDY, microseism and wind have decreased

SEI_CONF state: WINDY
Wind: 7mph Gusts, 6mph 5min avg

QUICK SUMMARY: No issues.
We have now had 2 locklosses from TURN_ON_BS_STAGE2. In both, the OM1 and OM2 offsets have been cleared (see attached images) so this wait timer has helped.
