An M9.3 flare (fairly strong-sized) along with a coronal mass ejection (CME) blasted out from the Sun and headed in the general direction of Earth (Aug. 4, 2011). This was the third flare in three days from Active Region 1261. The CME, in the 304 wavelength of extreme ultraviolet light, can be seen distinctly as a darker cloud lifting off and rising up and out into space, something we usually do not get to see so clearly. The movie covers about four hours of activity. It is predicted that the particle cloud will impact Earth in a few days, when it will likely generate bright auroras as far south as Pennsylvania and could possibly upset electronic equipment, especially in space. The power of the storm is ranked as K-7 on a 1-9 scale.https://blogger.googleusercontent.com/tracker/6369594138980582994-7031091424282787277?l=sdoisgo.blogspot.com
