Magnetic structure of solar active region NOAA 11158
P. Vemareddy, A. Ambastha, T. Wiegelmann
Magnetic fields in the solar corona are responsible for a wide range of phenomena. However, any direct measurements of the coronal magnetic fields are very difficult due to lack of…
Sub-Surface Meridional flow, Vorticity and the life time of Solar Active Regions
R. A. Maurya, A. Ambastha
Solar sub-surface fluid topology provides an indirect approach to examine the internal characteristics of active regions (ARs). Earlier studies have revealed the prevalence of stro…
Variations in -Mode Parameters with Changing Onset-Time of a Large Flare
R. A. Maurya, A. Ambastha, S. C. Tripathy
It is expected that energetic solar flares releasing large amount of energy at the photosphere may be able to excite the acoustic (-) modes of oscillations. We have determined t…
A Technique for Automated Determination of Flare-ribbon Separation and Energy Release
R. A. Maurya, A. Ambastha
We present a technique for automatic determination of flare-ribbon separation and the energy released during the course of two-ribbon flares. We have used chromospheric H filter…
