Fast CME and prominence eruption

image129

One of the fastest CMEs in years was captured by the STEREO COR1 telescopes on August 1, 2010. This movie, combining COR1-Ahead images with the simultaneous Helium II 304 Angstrom images from the STEREO EUVI telescope, shows the rapid explosion of material outward, followed by a slower eruption of a polar crown prominence from another part of the Sun. This CME is seen to be heading towards Earth at speeds well over 1000 kilometers per second.
