Humongous Eruption
A truly gigantic explosion happened on the sun yesterday. On Nov. 16th, magnetic fields snaking halfway across the sun’s southern hemisphere erupted in tandem, producing a prominence so big, it doesn’t fit inside this image from NASA’s Solar Dynamics Observatory (SDO):
The blast hurled a CME into space, but the cloud does not appear to be heading for Earth.
A movie of the event, prepared by Steele Hill of the Goddard Space Flight Center, shows magnetic fields in concerted motion across an expanse of solar “terrain” more than 700,000 km wide. Observations by SDO have shown that such wide-ranging eruptions are not uncommon on the sun–the great Global Eruption of August 2010 being the iconic example.Solar flare alerts: text, voice.http://www.spaceweather.com/
