The Possible Ascent of a Closed Magnetic System through the Photosphere
Bruce W. Lites,Boon Chye Low,V. Martínez Pillet,P. Seagraves,Andrew Skumanich,Z. Frank,R. A. Shine,Saku Tsuneta +7 more
Journal ArticleDOI
Stokes profile analysis and vector magnetic fields. VI: Fine scale structure of a sunspot
TL;DR: In this article, the vector magnetic field structure of a small, symmetric sunspot observed very close to disk center was explored using data from the High Altitude Observatory/National Solar Observatory Advanced Stokes Polarimeter (ASP).
Journal ArticleDOI
Active Region Magnetic Fields. I. Plage Fields
TL;DR: In this article, the frequency distribution of the magnetic field strength, inclination with respect to vertical (γ), azimuthal orientation (χ), and filling factor (f) is studied.
Journal ArticleDOI
Estimating the Sun's radiative output during the Maunder Minimum
TL;DR: In this article, a correlation between measured total solar irradiance (corrected for sunspot effects) and a Ca II surrogate for bright magnetic features was found, and it was estimated that the Sun's radiative output in the absence of such features to be 1365.43 w/m2, or 0.24% below its mean value for the 1980 to 1986 period.
