Sun erupted with double trouble on Nov 16
Washington: According to NASA, the Sun erupted with two prominence eruptions, one after the other over a four-hour period on Nov. 16, 2012, between the hours of 1 and 5 a.m. EST.
NASA's Solar Dynamic Observatory (SDO) captured the action in the 304 Angstrom wavelength of extreme ultraviolet light.
Scientists suggest that the disruption to the Sun’s magnetic field might have triggered the second event since they were in relatively close proximity to each other.
The red-glowing looped material is plasma, a hot gas made of electrically charged hydrogen and helium. The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma.
The expanding particle clouds heading into space do not appear to be Earth-directed.
