Red arcs, caused by magnetic storms, spotted for the first time in Italy
Red arcs over Europe: Astronomers capture bizarre phenomenon caused by magnetic storms for first time. Invisible to the naked eye, the arcs have been captured stretching from about 50 to 370 miles (85 to 600 kilometers) above the Earth, so high in the ionosphere, for the first time ever. Arcs are remnants of the magnetic storms that batter the Earth. Researchers had previously thought the phenomenon was obscured by light pollution.
This image shows on the left side the ‘all sky image’ of a glowing red arc invisible to the naked eye, and a low elevation shot showing the same phenomenon (right).The arcs have been detected high above most of Europe and these images were taken from Cima Ekar in Asiago, Italy on 26th September 2011.
