Continuing a week’s worth of substantial flares beginning on Oct.19, 2014, the sun emitted two mid-level solar flares on Oct. 26 and Oct. 27. The first (left), an M7.1-class, peaked at 8:34 pm EDT on Oct. 26, 2014, and the second (right), an M6.7-class, peaked almost 10 hours later at 6:09 am EDT on Oct. 27. NASA’s Solar Dynamics Observatory, which constantly observes the sun, captured images of both flares. The images show EUV light of 131 Angstroms, which is typically colorized in teal.
