Inter-planetary type-IV solar radio bursts: A comprehensive catalog and statistical results
Atul Mohan, Nat Gopalswamy, Anshu Kumari +2
Decameter hectometric (DH; 1-14 MHz) type-IV radio bursts are produced by flare-accelerated electrons trapped in post-flare loops or the moving magnetic structures associated with…
Intense Geomagnetic Storms during Solar Cycles 23-25
N. Gopalswamy, S. Akiyama, S. Yashiro +2
Intense geomagnetic storms are characterized by a minimum value of the Dst index at or below -100 nT. It is well known that these storms are caused by the southward magnetic fields…
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…
Effect of the Heliospheric State on CME Evolution
Fithanegest Kassa Dagnew, Nat Gopalswamy, Solomon Belay Tessema +2
The culmination of solar cycle 24 by the end of 2019 has created the opportunity to compare the differing properties of coronal mass ejections (CMEs) between two whole solar cycles…
What is Unusual about the Third Largest Geomagnetic Storm of Solar Cycle 24?
N. Gopalswamy, S. Yashiro, S. Akiyama +4
We report on the solar and interplanetary (IP) causes of the third largest geomagnetic storm (2018 August 26) in solar cycle 24. The underlying coronal mass ejection (CME) originat…
The 2012 July 23 Backside Eruption: An Extreme Energetic Particle Event?
Nat Gopalswamy, Seiji Yashiro, Neeharika Thakur +3
The backside coronal mass ejection (CME) of 2012 July 23 had a short Sun to Earth shock transit time (18.5 hours). The associated solar energetic particle (SEP) event had a >10 MeV…
