An Analysis of the Morphology of Pre- to Post-Flare Sunspot Flare Area Magnetic Field Contours
Abstract
Pre-flare conditions are characterized by a strong magnetic field in the active regions compared to that in the surrounding quiet regions. During the active phase, magnetic field (represented in the contour and brightness of magnetogram) around sunspot group shows the dynamics of the sunspots. The measurable parameter of the morphology of magnetic field up to the peak of their activity is the increase of magnetic flux and the spread of the bright region. While during post-flare, magnetogram contours decrease and sunspot groups disappear.
