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…
Major Solar Eruptions and High Energy Particle Events during Solar Cycle 24
N. Gopalswamy, H. Xie, S. Akiyama +2
We report on a study of all major solar eruptions that occurred on the front-side of the Sun during the rise to peak phase of cycle 24 (first 62 months) in order to understand the…
Ground Level Enhancement in the 2014 January 6 Solar Energetic Particle Event
N. Thakur, N. Gopalswamy, H. Xie +4
We present a study of the 2014 January 6 solar energetic particle (SEP) event, which produced a small ground level enhancement (GLE), making it the second GLE of this unusual solar…
The Relationship Between the Expansion Speed and Radial Speed of CMEs Confirmed Using Quadrature Observations of the 2011 February 15 CME
Nat Gopalswamy, Pertti Mäkelä, Seiji Yashiro +1
It is difficult to measure the true speed of Earth-directed CMEs from a coronagraph located along the Sun-Earth line because of the occulting disk. However, the expansion speed (th…
