NASA's Solar Dynamics Observatory took these images of the same X3.2-class flare from that erupted on May 13. NASA described the images:
"Starting in the upper left and going clockwise, the images show light in the 304-, 335-, 193-, and 131-angstrom wavelengths. By looking at the sun in different wavelengths, scientists can view solar material at different temperatures, and thus learn more about what causes flares."
