Solar atmospheric heating and topology of solar magnetic field.
Abstract
The photospheric vector magnetic fields, Hα and soft X-ray images of AR 7321 were simultaneously observed with the Solar Flare Telescope at Mitaka and the Soft X-ray Telescope of Yohkoh on October 26, 1992, when there were no drastic activities in this region. Taking the observed photospheric vector magnetic fields as the boundary condition, 3D magnetic fields above the photosphere were computed with a new extrapolation method. Since Yohkoh data and Mitaka data were obtained in well arranged time sequences during the day, the evolution of 3D fields, Hα features and soft X-ray features in this region can be studied in detail.
