Morning,
AO-51 heard well south of the TCA with Fromosat 3D.

So just how close was close?

It's all predictive until they smack together, but the estimates this morning said 893m overall, but only 39m radially. I'm visualizing that as one car merging on a highway at 17,500 mph, with one 3000 feet in front of, and 120 feet left or right of the other. Scale the 17,500 mph to 70 mph, and the distances in the analogy would be 12 feet in front of, and 6 inches abreast. Just to put the velocity and distances in perspective!

Of course, then a 12' long car would only be about 5/8" or 1.5 cm. Still, uncomfortably close.
