<p>Flares occur when accelerated charged particles, mainly electrons, interact with the <a href="page.php?w=Plasma_%28physics%29">plasma</a> medium. Evidence suggests that the phenomenon of <a href="page.php?w=magnetic_reconnection">magnetic reconnection</a> leads to this extreme acceleration of charged particles.
