A study of the kinematic and volumetric co-evolution of Earth-directed CMEs
Ashutosh Pattnaik, Nat Gopalswamy, Ranadeep Sarkar +3
While flare-associated CMEs generally show a strong association between flare X-ray flux and CME kinematics, their volumetric evolution and its link to both kinematics and flare ac…
Unusual Circumstances of the 2024 June 8 GLE
Nat Gopalswamy, Pertti Makela, Hong Xie +3
Ground Level Enhancement (GLE) in large solar energetic particle (SEP) events is indicative of protons accelerated to GeV energies. Almost all GLE events are associated with sustai…
Role of CME clusters and CME-CME interactions in producing sustained -ray emission
Atul Mohan, Pertti Makela, Natchimuthuk Gopalswamy +2
Fast (V>1000) coronal mass ejections (CMEs) capable of accelerating protons beyond 300MeV are thought to trigger hours-long sustained -ray emissi…
Novel scaling laws to derive spatially resolved flare and CME parameters from sun-as-a-star observables
Atul Mohan, Natchimuthuk Gopalswamy, Hemapriya Raju +1
Coronal mass ejections (CMEs) are often associated with X-ray (SXR) flares powered by magnetic reconnection in the low-corona, while the CME shocks in the upper corona and interpla…
A catalog of multi-vantage point observations of type-II bursts: Statistics and correlations
Atul Mohan, Nat Gopalswamy, Hemapriya Raju +1
Coronal mass ejection (CME) often produces a soft X-ray (SXR) flare associated with the low-coronal reconnection and a type-II radio burst associated with an interplanetary (IP) CM…
Interplanetary magnetic flux rope observed at ground level by HAWC
S. Akiyama, R. Alfaro, C. Alvarez +59
We report the ground-level detection of a Galactic Cosmic-Ray (GCR) flux enhancement lasting 17 hr and associated with the passage of a magnetic flux rope (MFR) over the Ear…
Source Regions of the Type II Radio Burst Observed During a CME-CME Interaction on 2013 May 22
P. Mäkelä. N. Gopalswamy, M. J. Reiner, S. Akiyama +1
We report on our study of radio source regions during the type II radio burst on 2013 May 22 based on direction finding (DF) analysis of the Wind/WAVES and STEREO/WAVES (SWAVES) ra…
