A bright and expansive coronal mass ejection (CME) unfurled itself on January 24, 2007. As seen in SOHO's LASCO C2 coronagraph, the bright front emerged in the shape of an arc from behind the occulting disk but soon expanded into a ragged, bulbous shape with lots of structural lines inside it. The source of this CME was an active region that had just began to rotate into view the next day. An EIT 304 Angstrom image of the Sun taken at nearly the same time was enlarged and superimposed on the occulting disk.
