This report on Wired.com includes audio of the roar of a tiny, but earth facing solar flare as it drowned out radio communications.  Adam Mann reports:

“Over the weekend, a tiny spot on the sun erupted into a moderately sized solar flare that was particularly loud in radio waves. With the sound of a roaring wave, it completely drowned out radio communication all over the Earth between 28 MHz and 21.1 MHz.

Amateur radio astronomer Thomas Ashcroft, who also works for NASA’s Radio Jove project,  provided the recording, according to the Wired article.  It’s intense as the roar meets earth’s ionosphere.  Mann writes:

“The radio burst that happened on Feb. 2 accelerated electrons to high energies. This electron stream created plasma and radio waves in the sun’s atmosphere, which traveled to Earth and disrupted some communications.”
