Space Watch – NASA detects X 2-class flare eruption on the Sun

Posted on November 5, 2011


November 4, 2011 – X-FLARE: Earth-orbiting satellites have just detected an X2-class solar flare. The source is huge sunspot AR1339. If a CME occurred, chances are it is not earth-directed given the far eastern eruption site on the solar disk NOAA said.

This turbulent region of the Sun will be facing Earth directly in about 5 days. A solar flare is a sudden brightening observed over the Sun surface or the solar limb, which is interpreted as a large energy release of up to 6 × 1025 joules of energy (about a sixth of the total energy output of the Sun each second).

The flare ejects clouds of electrons, ions, and atoms through the corona into space. These clouds typically reach Earth a day or two after the event. The term is also used to refer to similar phenomena in other stars, where the term stellar flare applies. -Wikipedia
