Scientific paper

Coronal mass ejections (CMEs) are a magnetic eruptions that carry 1023 Wb of magnetic flux and 1015\-- 16~g of material into interplanetary space with a kinetic energy of 1031\--32 ergs and represent the dominant source of non-recurrent geomagnetic storms. Quantifying and understanding CME kinematics is fundamental for testing theoretical models of CME propagation. We propose a heuristic Newtonian model for quantifying impulsive CME dynamics and investigate CMEs observed by Large Angle Spectrometric Coronagraph (LASCO) augmented with observations of eruptive prominences observed by the Extreme Ultraviolet Imaging telescope (EIT), Nobeyama Radioheliograph (NRoH), Big Bear Solar Observatory (BBSO), and Kanzelhöehe Solar Observatory (KSO). Work supported by NASA and ONR.
