NASA | Five Days of Flares and CMEs

This movie shows 23 of the 26 M- and X-class flares on the sun between 1800 UT Oct. 23 and 1500 UT Oct. 28, 2013, as captured by NASA's Solar Dynamics Observatory. It also shows the coronal mass ejections -- great clouds of solar material bursting off the sun into space -- during that time as captured by the ESA/NASA Solar and Heliospheric Observatory.
