Lockloss 21:28 UTC
Unknown cause lockloss. Could be attributed to the wind, since it is on the rise and expected to continue tonight. Gusts were over 30mph at the time of the lockloss.
It seems that there was a length kick in EY that was first seen causing the lockloss. Lockloss report.
This lockloss could have been caused by some ring up that appears to be at a frequency between 11-13 Hz in the LSC loops.
