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…
Deflection and Rotation of CMEs from Active Region 11158
C. Kay, N. Gopalswamy, H. Xie +1
Between the 13 and 16 of February 2011 a series of coronal mass ejections (CMEs) erupted from multiple polarity inversion lines within active region 11158. For seven of these CMEs…
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…
