Flare activity, sunspot motions, and the evolution of vector magnetic fields in Hale region 17244
Abstract
We study the magnetic and dynamical circumstances leading to the 1B/M4 flare of November 5, 1980, and find a strong association between the buildup of magnetic shear and the onset of flare activity within the active region. The development of shear, as observed directly in vector magnetograms, is consistent in detail with the dynamical history of the active region and identifies the precise location of the optical and hard x-ray kernels of the flare emission.
