Flurry Of Flares
A single, dynamic active region unleashed over half a dozen solar flares in about one day (Aug. 25-26, 2014). The two larger flares were M-class (moderate) flares and the others were smaller flares. The images were taken in a wavelength of extreme ultraviolet light that is well designed to observe flares: this channel (at 131 Angstroms) can measure extremely hot temperatures up to 10 million degrees C. Some coronal mass ejections were also associated with the flares.
