This is a great story that shows the value of creativity and ingenuity. An Austrialian undergraduate student had the brilliant idea of dividing the inputs from a wide field of radio telescopes and processing them as if they were the eyes of a gigantic observer and was thereby able to image structures in the atmosphere that have thus far only been the subject of speculation.

I like the "could affect some civilian and military navigation systems ".

I wonder if it really does affect GNSS?

I don't see why not. It's a presently unmodelled variation in the ionosphere.

Thanks for the link.

Shared this with both my kids (12 and 9). Kinda tough for me to explain a plasma but, their school has fostered an interest in astronomy. That made for a good jumping off place from monoscopic observations (standard telescopes and my total station) to the stereoscopic wingding she unleashed.

Equipotential arches of ions, eh? Did they know that when they started shoving rockets through there?

Had to. At least in theory.
