An eruption on the surface of the Sun has produced a burst of energy in the range of 18 to 22 MHz. One that Astronomer Thomas Ashcraft says sounded like a freight train rolling through the area.

According to Spaceweather.com, this active sunspot has been hiding just behind the sun's eastern most branch. For days it had been ejecting clouds of magnetized gas high above the Suns surface. It was expected to emerge into sight of Earth on Tuesday November 7th or early on Wednesday, the 8th .

Astronomer Ashcroft recorded the sound of the approaching solar storm using a radio telescope in New Mexico. You can hear what it sounds like by taking your web browser to http://www.heliotown.com/Snov6_06_1747ut1822.mp3 (Spaceweather.com))
