Large Solar Flares Erupt From the Sun

NASA’s Solar Dynamics Observatory captured images of solar flares on Nov. 14 and Nov. 30, 2025. The orange and yellow sequence (left) shows a subset of ultraviolet light, highlighting the extreme temperature of the material in the flare. The Nov. 14 flare (right) is displayed in the 131-angstrom wavelength and colorized in teal. This channel helps pinpoint solar material at temperatures of about 18 million degrees Fahrenheit (10 million Kelvin), which is characteristic of the superheated plasma in flares. The flare on the left is classified as an X1.9 flare, while the flare on the right is classified as an X4.0 flare. X-class denotes the most intense flares, while the number provides more information about its strength.
