42. Speed of CMEs and the Magnetic Non-potentiality of Their Source Active Regions
A statistical study using HMI vector magnetograms predicts the fastest CME that an active region can produce based on its magnetic parameters.
37. Why is the Great Solar Active Region 12192 Flare-Rich but CME-Poor?
AR 12192 produced six X-class flares, but none was associated with a CME. HMI observations reveal the mild nature of the giant. It has weak relative non-potentiality and strong overlying field; the confined X3 flare leaves little imprint on the photosphere.
