Class X2 Solar FlareCredit: NASA SOHOThe image of the powerful Class X2 solar flare of Feb. 14, 2011, shows how it appeared to both the Solar Dynamics Observatory in extreme ultraviolet light (center sun disk) and the SOHO's C2 coronagraph. This was the largest flare in more than four years.
Monster ProminenceCredit: NASA/SDO
NASA's Solar Dynamics Observatory captured this view of a powerful M3.6 Class solar flare on Feb. 24, 2011 during a 90-minute sun storm. NASA scientists called the display a "monster prominence" that kicked up a huge plasma wave.
Sun Unleashes X1.5-Class FlareCredit: NASA/SDO/GSFCThe sun unleashed a powerful Class X1.5 solar flare on March 9, 2011, a solar storm that could supercharge Earth's auroras. The flare was recorded by NASA's Solar Dynamics Observatory and other spacecraft. Here, it appears in white at the upper right of the sun as seen by the Solar Dynamics Observatory
The First Time I Ever Saw Your FaceCredit: NASAA full-disk multiwavelength extreme ultraviolet image of the sun taken by SDO on March 30, 2010. False colors trace different gas temperatures. Reds are relatively cool (about 60,000 Kelvin, or 107,540 F); blues and greens are hotter
Shooting UpCredit: NASA/GSFCA prominence leaps off the surface of the sun in this new image from NASA's Solar Dynamics Observatory released on April 22, 2010. The prominence occurred on March 30

Floating FreeCredit: NASAThe STEREO (Ahead) spacecraft observed this visually stunning prominence eruption on Sept. 29, 2008 in the 304 wavelength of extreme UV light. It rose up and cascaded to the right over several hours, appearing something like a flag unfurling, as it broke
