Solar Dynamics Observatory Image

Caption

This image from the Atmospheric Imaging Assembly on board NASA's Solar Dynamics Observatory was taken simultaneously with the IRIS observations. It shows emission from hot coronal loops (T > 5 million K) in a solar active region. IRIS observed brightenings occurring at the footpoints of these hot loops. The image is color-coded to show light at a wavelength of 94 Angstroms. The size of each pixel corresponds to about 430 km (270 miles) on the Sun.
