Coronal Mass Ejection

CME Initiation, Evolution, and Interplanetary Consequences

HAO scientists have carried out 3D isothermal MHD simulations of the evolution of the large scale coronal magnetic field as a twisted magnetic flux tube is driven (slowly) through the lower boundary into a pre-existing coronal arcade field.

NCAR solar physicist Scott McIntosh is raising awareness. While the current peak in the 11-year cycle of sunspot activity is on the weak side, the Sun might still produce a major storm at any point.
