The Balloon-borne Investigation of Temperature and Speed of Electrons in the corona (BITSE): Mission Description and Preliminary Results
N. Gopalswamy, J. Newmark, S. Yashiro +16
We report on the Balloonborne Investigation of Temperature and Speed of Electrons in the corona (BITSE) mission launched recently to observe the solar corona from about 3 Rs to 15…
Source of Energetic Protons in the 2014 September 1 Sustained Gamma-ray Emission Event
N. Gopalswamy, P. Mäkelä, S. Yashiro +3
We report on the source of greater than 300 MeV protons during the SOL2014-09-01 sustained gamma-ray emission (SGRE) event based on multi-wavelength data from a wide array of space…
Sun-to-Earth Propagation of the 2015 June 21 Coronal Mass Ejection Revealed by Optical, EUV, and Radio Observations
N. Gopalswamy, P. Makela, S. Akiyama +3
We investigate the propagation of the 2015 June 21 CME-driven shock as revealed by the type II bursts at metric and longer wavelengths and coronagraph observations. The CME was ass…
A Hierarchical Relationship between the Fluence Spectra and CME Kinematics in Large Solar Energetic Particle Events: A Radio Perspective
N Gopalswamy, P Mäkelä, S Yashiro +3
We report on further evidence that solar energetic particles are organized by the kinematic properties of coronal mass ejections (CMEs)[1]. In particular, we focus on the starting…
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…
A Study of the 2012 January 19 Complex Type II Radio Burst Using Wind, SOHO, and STEREO Observations
T. B. Teklu, A. V. Gholap, N. Gopalswamy +5
We report on a case study of the complex type II radio burst of 2012 January 19 and its association with a white light coronal mass ejection (CME). The complexity can be described…
