On August 31, 2012 the Sun threw a major tantrum. It started with a vast arc of material towering over its surface, a stream of plasma flowing between two sunspots. Sometimes these collapse back down to the Sun’s surface, but this one exploded, blasting hundreds of millions of tons of material out into space. SDO captured this ridiculously awesome picture of the arc just before it erupted!


Flat Earth Ocean Tide Theory: Water Is diamagnetic, meaning it repels a magnetic field. The close sun is a positive electromagnetic energy repelling the water in the ocean, creating low tides and and the moon is a negative electromagnetic energy causing high tides. - Wrong - Water is only very weakly repelled by a magnetic field not attracted. If any of this were true we would experience huge tidal changes during Sunspot activity (magnetic storms)…

The northern lights are more formally known as auroras, and are caused by interactions between the solar wind and the Earth's magnetic field.


X-FLARE! Earth orbiting satellites have just detected another strong solar flare, this one from departing sunspot AR1875. The blast, which peaked on Oct. 29th at approximately 2148 UT (02:48 PDT), measured X2 on the Richter Scale of Solar Flares. NASA Solar Dynamics Observatory recorded the extreme ultraviolet flash.
