Degree of electric current neutralization and the activity in solar Active Regions
P. Vemareddy
Using time-sequence vector magnetic field observation from \textit{Helioseismic and Magnetic Imager}, we examined the connection of non-neutralized currents and the observed activi…
Comparison of magnetic properties in a magnetic cloud and its solar source on April 11-14 2013
P. Vemareddy, C. Möstl, T. Rollett +3
In the context of Sun-Earth connection of coronal mass ejections and magnetic flux ropes (MFRs), we studied the solar active region (AR) and the magnetic properties of magnetic clo…
Sunspot Rotation as a Driver of Major Solar Eruptions in NOAA Active Region 12158
P. Vemareddy, X. Cheng, B. Ravindra
We studied the developing conditions of sigmoid structure under the influence of magnetic non-potential characteristics of a rotating sunspot in the active region (AR) 12158. Vecto…
Quasi-Static 3D-Magnetic Field Evolution in Solar Active Region NOAA 11166 Associated with X1.5 Flare
P. Vemareddy, T. Wiegelmann
We study the quasi-static evolution of coronal magnetic fields constructed from the Non Linear Force Free Field (NLFFF) approximation aiming to understand the relation between the…
