Halo CMEs Galore
The Sun produced four halo coronal mass ejections (CMEs) in just three days as well as several other eruptions (Sept. 27-29, 2012). Halo CMEs are called that because the leading edge of the particle clouds appears to expand in a circle around the Sun. The source of the CME was either near the center of the Sun on the front side (facing Earth) or the far-side. Three of the halo CMEs were determined to be from the far-side. The one early on September 28th originated from an active region on the front-side. The video clip was taken by the LASCO C3 instrument with frames every 12 minutes.
