OPS Midshift Report
Wind is still high. Microseism is rising now.
Managed a 2-minute DRMI lock and that's the highest we've gotten today. If we continue failing and the wind/microseism stays high, I will go into IDLE again until I see any improvements.

Just reached NLN - but worried that we will lose lock in the next 9 minutes due to the 1Hz ringup.
If Ryan S is correct about the lock acquisition time/thermalizing correlation with the lockloss-causing ringups, this lock definitely falls into the category for LL - we shall see. alog 87557

Still unable to get past DRMI despite good looking alignment. Made the decision to sit in IDLE. Wind is high but is lowered to around 30+ gusts though microseism is now over the 90th percentile and rising.

Yep - Lockloss after 4 minutes due to the ringup.

Wind is forecasted to come down this evening.
