We examine the magnetic structures in AR 6659 by using the observatibn of vector magnetic fields obtained at Marshall Space Flight Center/National Aeronautics and Space Administration (MSFC/NASA). Using these vector magnetic field data as the input f

We report the result of a study of magnetic helicity in solar active regions during 1980-2000. Using the vector magnetograms from four instruments (Haleakala Stokes Polarimeter, Marshall Space Flight Center, Mitaka Solar Flare Telescope and Okayama O

An algorithm has been developed to extrapolate nonlinear force-free magnetic fields from the photosphere, given the proper boundary conditions. This paper presents the results of this work, describing the mathematical formalism that was developed, th

The Ultraviolet Spectrometer and Polarimeter on the Solar Maximum Mission spacraft has observed for the first time the longitudinal component of the magnetic field by means of the Zeeman effect in the transition region above a sunspot. The data prese

A self-consistent magnetohydrodynamic (MHD) model of shearing magnetic loops is used to investigate magnetic energy buildup in active region AR 2372 (Boulder number), in the period of 5–7 April, 1980. The magnetic field and sunspot motions in this

A new hybrid partition function is used to calculate the quantum‐statistical behavior of the various isotopes and nuclear‐spin isomers of diatomic hydrogen interacting with a plane structureless surface. Problems of convergence usually encountere

We review the use of polarimetric techniques in measurements of the magnetic field in the sun’s atmosphere. The basic principles of the inverse Zeeman effect and the radiative transfer of polarized light are presented to demonstrate how the vector
