Implosions in Coronal Transients

Abstract

Coronal events such as flares or coronal mass ejections derive their energy from the energy stored locally in the magnetic field. This leads to the conjecture that a magnetic implosion must occur simultaneously with the energy release. The site of the implosion would show the location of preflare energy storage, and its detection should have a high priority. The Transition Region and Coronal Explorer EUV observations, for example, have sufficient resolution to show the geometry of a flare implosion by following the motions of tracers in the images.
