This movie shows you how two of the three instruments observed the X2 solar flare on February 15, 2011.
Sunspot 1158 unleashed the strongest solar flare in more than four years. The eruption, which peaked at 0156 UT on February15th registered X2 on the Richter scale of solar flares.
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.
