A Sun-to-Earth analysis of magnetic helicity of the 17-18 March 2013 interplanetary coronal mass ejection
Sanchita Pal, Nat Gopalswamy, Dibyendu Nandy +4
We compare the magnetic helicity in the 17-18 March 2013 interplanetary coronal mass ejection (ICME) flux-rope at 1 AU and in its solar counterpart. The progenitor coronal mass eje…
A new technique to provide realistic input to CME forecasting models
Nat Gopalswamy, Sachiko Akiyama, Seiji Yashiro +1
We report on a technique to construct a flux rope (FR) from eruption data at the Sun. The technique involves line-of-sight magnetic fields, post-eruption arcades in the corona, and…
A Hierarchical Relationship between the Fluence Spectra and CME Kinematics in Large Solar Energetic Particle Events: A Radio Perspective
N Gopalswamy, P Mäkelä, S Yashiro +3
We report on further evidence that solar energetic particles are organized by the kinematic properties of coronal mass ejections (CMEs)[1]. In particular, we focus on the starting…
Coronal Flux Ropes and their Interplanetary Counterparts
N. Gopalswamy, S. Akiyama, S. Yashiro +1
We report on a study comparing coronal flux ropes inferred from eruption data with their interplanetary counterparts constructed from in situ data. The eruption data include the so…
Estimation of Reconnection Flux using Post-eruption Arcades and Its Relevance to 1-au Magnetic Clouds
N. Gopalswamy, S. Yashiro, S. Akiyama +1
We report on a new method to compute the flare reconnection (RC) flux from post-eruption arcades (PEAs) and the underlying photospheric magnetic fields. In previous works, the RC f…
