Thanks for spelling it out. That was my thought too: if the flare was just this morning how could it already have caused a radio blackout?

I imagine the author is actually talking about the 186,000 miles per second electromagnetic emissions associated with the flare disrupting communications eight minutes after the eruption this morning and the 600 miles per second particles arriving late tomorrow or early the following morning. That's just a guess. It's left to the reader to infer what the illiterate journalist would have said if he understood math, science, and English well enough to present the facts coherently.

Happens all the time... even people who really know better fail to chck this type of figure.
Missing zero. I'm guessing 6000 Mps is correct, rather than 600.
