Understanding Flux Rope Driven Coronal Waves and Mass Ejections from X2.3 Solar Flare

This study explores the dynamics of coronal waves and mass ejections initiated by an X2.3 solar flare. Utilizing observations from the TRACE spacecraft, we analyze the progression of a wavefront driven by a flux rope, which ultimately precedes a coronal mass ejection (CME). As CMEs can pose significant risks to Earth and satellites, especially when associated with large solar flares, comprehending their origins is crucial. This research highlights the relationship between flares, CMEs, and their wavefronts, enhancing preparedness for potential hazardous space weather events.

  1. Flux Rope Driven Coronal Waves / Mass Ejections An X2.3 Solar Flare explosively drives a flux rope. Observations using the TRACE spacecraft (top) illustrate the progression of a wavefront which is apparently driven by the flux rope. This wavefront is produced by the skirt of an expanding Coronal Mass Ejection (CME), which in turn is produced by a piston shock overlaying the erupting flux rope, and ultimately drives the CME. CME can hit the Earth and our satellites with hazardous consequences, particularly fast CME which are often associated with large flares such as this X Class event. Understanding the origins of coronal waves and their association with both flares and CME enables us to better understand the whole CME process, and thus be in a better position to prepare for particularly hazardous events.
