High-energy solar particle events in cycle 24
Nat Gopalswamy, Pertti Makela, Seiji Yashiro +3
The Sun is already in the declining phase of cycle 24, but the paucity of high-energy solar energetic particle (SEP) events continues with only two ground level enhancement (GLE) e…
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…
