On Properties of Energetic Coronal Mass - Flare Events
ABSTRACT In the present paper, the properties of more energetic coronal mass ejections (ECMEs) (kinetic energy ≥1E + 30 ergs) observed between the years from 1996 to 2006 were studied. Through this period and under certain time-based and spatial conditions 253 Flare-ECMEs were selected . These 253 energetic CME-Flare events separated into two groups according to their time of detection, Before Flare-ECME events and After Flare–ECME event. This study indicates that the mean CME width for both before and after Flare-ECMEs are 90 and 100 degrees, respectively. Also, it was found that the before Flare-ECMEs are in average faster than the after Flare-ECMEs. The results show also both before and after Flare-ECMEs are wider than other CMEs. Besides it was found that the before Flare-ECMEs are in average faster than the after Flare-ECMEs, while the after Flare-ECMEs are in average more massive than before Flare – ECMEs. Finally it was found that both after and before Flare-ECMEs has negative mean acceleration.
