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…
What do halo CMEs tell us about solar cycle 25?
Nat Gopalswamy, Grzegorz Michalek, Seiji Yashiro +3
It is known that the weak state of the heliosphere due to diminished solar activity in cycle 24 back-reacted on coronal mass ejections (CMEs) to make them appear wider for a given…
The Solar Cause of the 2022 February 3 Geomagnetic Storm that Led to the Demise of the Starlink Satellites
Nat Gopalswamy, Hong Xie, Seiji Yashiro +1
We report on the solar source of the 2022 February 3 geomagnetic storm of moderate strength that contributed to the loss of 39 Starlink satellites. The geomagnetic storm was caused…
The Relation between Type III Radio Storms and CIR Energetic Particles
Nat Gopalswamy, Pertti Mäkelä, Seiji Yashiro +2
We report on a study that compares energetic particle fluxes in corotating interaction regions (CIRs) associated with type III radio storm with those in nonstorm CIRs. In a case st…
Can Type III Radio Storms be a Source of Seed Particles to Shock Acceleration?
Nat Gopalswamy, Sachiko Akiyama, Pertti Mäkelä +2
An intense type III radio storm has been disrupted by a fast halo coronal mass ejection (CME) on 2000 April 4. The CME is also associated with a large solar energetic particle (SEP…
