ESA SOHO – Five for Five
April 4, 2012
The Sun blew out at least five halo coronal mass ejections (CMEs) and several others over a five-day period (Mar. 24-29, 2012). SOHO’s C3 coronagraph observed the action. Halo CMEs are ejections whose leading edge appears to spread out from the Sun in a kind of circle (i.e., halo), which indicates that the expanding cloud of particles is heading either directly towards or away from Earth. credit: ESA
