Study of Solar Energetic Particles: their Source Regions, Flares and CMEs during Solar Cycles 23-24
Raj Kumar, Ramesh Chandra, Bimal Pande +1
In this work, we examine the association between solar active regions and 152 solar flares, coronal mass ejections, and solar energetic particle (SEP) events over solar cycles 23-2…
Data-Constrained Magnetohydrodynamics Simulation of a Confined X-class Flare in NOAA Active Region 11166
Sanjay Kumar, Pawan Kumar, Sadashiv +5
In this paper, we present a magnetohydrodynamics simulation of NOAA active region 11166 to understand the origin of a confined X-class flare that peaked at 23:23 UT on 2011 March 9…
Large-Amplitude Longitudinal Oscillations Triggered by the Merging of Two Solar Filaments: Observations and Magnetic Field Analysis
M. Luna, Y. Su, B. Schmieder +2
We follow the eruption of two related intermediate filaments observed in H (from GONG) and in EUV (from SDO/AIA) and the resulting large-amplitude longitudinal oscillations of t…
How can a Negative Magnetic Helicity Active Region Generate a Positive Helicity Magnetic Cloud ?
R. Chandra, E. Pariat, B. Schmieder +2
The geoeffective magnetic cloud (MC) of 20 November 2003, has been associated to the 18 November 2003, solar active events in previous studies. In some of these, it was estimated t…
Major Surge Activity of Super-Active Region NOAA 10484
W. Uddin, P. Kumar, A. K. Srivastava +1
We observed two surges in H-alpha from the super-active region NOAA 10484. The first surge was associated with an SF/C4.3 class flare. The second one was a major surge associated w…
