Diffuse Interplanetary Radio Emission: Shock Emission or a Type III storm?
Nat Gopalswamy, Sachiko Akiyama, Pertti Mäkelä +1
We present a clear case of a Diffuse Interplanetary Radio Emission (DIRE) event observed during 2002 March 11-12 in association with a fast coronal mass ejection (CME). In the prev…
Effect of the Weakened Heliosphere in Solar Cycle 24 on the Properties of Coronal Mass Ejections
N. Gopalswamy, S. Akiyama, S. Yashiro +3
Solar cycle (SC) 24 has come to an end by the end of 2019, providing information on two full cycles to understand the manifestations of SC 24, the smallest cycle in the Space Age t…
The shock driving capability of a CME inferred from multiwavelength observations
Fithanegest Kassa Dagnew, Nat Gopalswamy, Solomon Belay Tessema +4
The radial speed of a coronal mass ejection (CME) determines the shock-driving capability of a CME as indicated by the presence of a type II radio burst. Here we report on the Apri…
On the properties of solar energetic particle events associated with metric type II radio bursts
Pertti Mäkelä, Nat Gopalswamy, Hong Xie +3
Metric type II solar radio bursts and solar energetic particles (SEPs) are both associated with shock fronts driven by coronal mass ejections (CMEs) in the solar corona. Recent stu…
