Sun Packs Double Punch

On August 3, the sun packed a double punch, emitting a M6.0-class flare at 9:43 am EDT. This video is of the second, slightly stronger M9.3-class flare at 11:41 pm EDT. Both flares had significant coronal mass ejections (CMEs) associated with them that will give the Earth a glancing blow. credit: NASA
