Evolution properties of the magnetic field structure of the flaring active region HR 16 631 and associated solar wind phenomena on February 2-6, 1980
Abstract
Helios 1 and 2, ISEE-3, and interplanetary scintillation data are examined in order to reveal the physical characteristics and 3D-structure of the extreme disturbance of the solar wind on 5-6 Feb. 1980. The disturbance and associated comet and earth's magnetosphere phenomena were shown to be due to the solar flare on February 3 at 13 h 38 m UT in active region HR 16,631. The magnetographic and radioastronomical investigations have revealed unusual evolution properties of this region before the flare: rapid evolution and complex configuratlon of the magnetic field, and the existence of a radio source with peculiar spectral-polarization characteristics testifying to the abnormal local release of energy in the corona.
