Two X Flares in Quick Succession

A powerful active region just rotating into view produced two X-class flares (the strongest category) about an hour apart on June 9, 2014. An X-2.3 flare peaked at 11:52 UT followed by an X-1.5 flare at 12:52 UT. This image shows the first of the two flares. The same active region produced another X class flare and a medium (M-class) flare the following day. Credit: NASA/Goddard/Solar Dynamics Observatory NASA image use policy.
