The Influence of Explosive Processes in Active Regions on the Characteristics of the Magnetic Field in the Umbra of Sunspots Depending on Their Size and Position

Abstract

In a series of studies, the authors have shown that explosive processes (EPs) in active regions (ARs) (such processes include solar flares and coronal mass ejections) can have a significant impact on the characteristics of the magnetic field in the umbra of some sunspots in these ARs. This paper is the first in a planned series of studies in which we will consider various factors that determining the extent of EP influence on the magnetic field in the umbra of sunspots. Using the example of one EP event, we attempted to determine how the size of the sunspots and their position relative to the location of the flare affect the intensity of EP impact on the magnetic field in the umbra of the sunspots.
