APOD - AR 3664 at the Sun's Edge

C'est ce genre d'éruption qui ensuite, quand elle touche la Terre peut faire plein d'aurores boréales.

What did the monster active region that created the recent auroras look like when at the Sun's edge? There, AR 3664 better showed its 3D structure. Pictured, a large multi-pronged solar prominence was captured extending from chaotic sunspot region AR 3664 out into space, just one example of the particle clouds ejected from this violent solar region.
