Sunspot 1158 has unleashed the strongest solar flare in more than four years. The eruption, which peaked at 0156 UT on Feb. 15th, registered X2 on the Richter scale of solar flares.
NASA's Solar Dynamics Observatory recorded an intense flash of extreme ultraviolet radiation.

X-flares are the strongest type of solar flare, and this is the first such eruption of new Solar Cycle 24. In addition to flashing Earth with UV radiation, the explosion also hurled a coronal mass ejection (CME) in our direction. The expanding cloud may be seen in this movie from NASA's STEREO-B spacecraft. Geomagnetic storms are possible when the CME arrives 36 to 48 hours hence. Stay tuned for updates.
This plasma filament above the Sun erupted as seen in this video by the Solar Dynamics Observatory. The eruption is in the upper right region of the solar disc. After it erupts, look to the left of center, at the top, for another plasma ejection. This view is at the 304-Angstrom and 193-Angstrom wavelengths. (Best viewed in Full Screen HD - full-screen)
The following video captures the massively large plasma filament 'erupion' from 12 December 2010.
A huge filament above the Sun erupted in an amazing display as seen in this video by the Solar Dynamics Observatory at approximately 1535 UTC (Dec 6, 2010). The eruption is in the lower left region of the solar disc, and you will see it toward the end of the video. This view is at the 304-Angstrom wavelength. (Best viewed in Full Screen HD - full-screen)
The next movie is of the Sun from Nov 15 to Dec 6 2010, as seen by SDO AIA at the 171 and 304 Angstrom wavelengths:
A rotation view of the full solar disc, as seen by the Solar Dynamics Observatory between November 15 and December 6, 2010. The view is a combination of the 171-Angstrom wavelength and 304-Angstrom wavelength filters of the SDO AIA instruments.
Notice the huge plasma "snakes" in the southern hemisphere (at several periods, including the very end of the rotation). These plasma filaments are incredibly large!
