An analysis of changes in the magnetic field of active region 9415 after the 2001 April 6 Solar Flare
… of the correlation between solar flares and magnetic flux change. The average gradient of the magnetic flux around the neutral line of Active Region 9415 and the locations of the magnetic flux centers-of-mass in both polarities in AR 9415 were determined. Subsequent to the 2001 April 6 flare, …

Automatic prediction of solar flares and super geomagnetic storms
… on space system, satellite-based services. A geomagnetic storm, a disturbance in Earth's magnetosphere, may produce many harmful effects on Earth. Solar flares and Coronal Mass Ejections (CMEs) are believed to be the major causes of geomagnetic storms. Thus, establishing a real time forecasting …

Investigation of model micro-scale reconnecting plasma modes
… which can have finite wavelength parallel to the magnetic field, is found in the limit of a straight and uniform magnetic field in the presence of temperature gradients. The theory of the related micro-reconnecting modes has been previously developed in view of explaining the observation of …

Discontinuous Galerkin modeling of plasma turbulence in a simple magnetized torus
… method. SMTs are physical approximations of a sheared cylinder and, with simple magnetic geometry and extensive diagnostics, are useful for validating numerical models. With helical, open field lines and magnetic shear, the Helimak is a good model of the plasma turbulence in the scrape-off …

A study of reversed shear Alfvén eigenmodes in Alcator C-Mod with phase contrast imaging
Shear Alfvén waves are a fundamental mode of magnetized plasma oscillation and may exist in tokamak plasmas as eigenmodes with a global structure and discrete frequencies. The inhomogeneity of the plasma profiles in conjunction with tokamak geometry tends to focus the Alfvén waves in regions of …

The Equilibria, Stability and Nonlinear Dynamics of Magnetically Sheared Atmospheres With Applications to the Solar Environment
… equilibria, stability and nonlinear dynamics of magnetically-sheared atmospheres as they relate to magnetic flux emergence and the structure and disruption of magnetic arcades of the sun. To begin this study, two families of analytical solutions describing isothermal magnetostatic atmospheres in …

High resolution studies of complex solar active regions
… events are produced in sunspots with a complex magnetic field topology. Studying their morphology and dynamics is helpful in understanding the energy accumulation and release mechanisms for flares and CMEs, which are intriguing problems in solar physics. The study of complex active regions is …

A Study of Reconnection Poleward of the Cusp: Cluster and Polar
… with in-situ observations, particularly at high magnetic latitudes. By the structure of the IDR we refer to features such as the non-colocation of the X-line and stagnation line, the distortion of the Hall magnetic and electric fields, outflow speed, outflow density etc. We have compiled a …
