Magnetic field dynamics in the active region in the early stage of development
Abstract
Using observations obtained with the vector-magnetograph of the Sayan observatory the authors have studied the dynamics of the magnetic field in the stage of appearance and formation of the active region SD 135/1984. A study is made of the evolution of a magnetic field subsystem at the center of the active region. It is concluded that the disappearance of this subsystem at the photospheric level - once the active region reaches its maximum development stage - may be accounted for by the emergence of a twisted (branched rather than dense) main flux tube into higher levels of the solar atmosphere.
