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…
A Study of the 2012 January 19 Complex Type II Radio Burst Using Wind, SOHO, and STEREO Observations
T. B. Teklu, A. V. Gholap, N. Gopalswamy +5
We report on a case study of the complex type II radio burst of 2012 January 19 and its association with a white light coronal mass ejection (CME). The complexity can be described…
On the Directivity of Low-Frequency Type IV Radio Bursts
Nat Gopalswamy, Sachiko Akiyama, Pertti Mäkelä +2
An intense type IV radio burst was observed by the STEREO Behind (STB) spacecraft located about 144 degres behind Earth. The burst was associated with a large solar eruption that o…
The Peculiar Behavior of Halo Coronal Mass Ejections in Solar Cycle 24
N. Gopalswamy, H. Xie, S. Akiyama +3
We report on a remarkable finding that the halo coronal mass ejections (CMEs) in cycle 24 are more abundant than in cycle 23, although the sunspot number in cycle 24 has dropped by…
Large Solar Energetic Particle Events Associated with Filament Eruptions Outside of Active Regions
N. Gopalswamy, P. Makela, S. Akiyama +4
We report on four large filament eruptions (FEs) from solar cycles 23 and 24 that were associated with large solar energetic particle (SEP) events and interplanetary type II radio…
