Solar flares result from some electromagnetic instability that occurs within regions of relatively strong magnetic field in the Sun's atmosphere. The processes that enable and …
KD Leka, G Barnes - The Astrophysical Journal, 2003 - iopscience.iop.org
Photospheric vector magnetic field data from the University of Hawai'i Imaging Vector Magnetograph, with good spatial and temporal sampling, are used to study the question of …
S Bao, H Zhang - The Astrophysical Journal, 1998 - iopscience.iop.org
Using a 1988–1997 data set of original photospheric vector magnetograms from the Solar Magnetic Field Telescope (SMFT) of the Huairou Solar Observing Station of Beijing …

In this study we use the ordinal logistic regression method to establish a prediction model, which estimates the probability for each solar active region to produce X-, M-, or C-class …
VI Abramenko, T Wang, VB Yurchishin - Solar Physics, 1996 - Springer
The problem of (dc) magnetic field energy build up in the solar atmosphere is addressed. Although large-scale current generation may be due to large-scale shearing motions in the …

Coronal mass ejections (CMEs) are large-scale expulsions of coronal plasma and magnetic field propagating through the heliosphere. Because CMEs are observed by white-light …

ABSTRACT A model for solar flares is proposed in which the flare energy is the magnetic energy released when two current-carrying flux loops reconnect to form two new current …
