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…
Properties of DH Type II Radio Bursts and Their Space Weather Implications
N. Gopalswamy, P. Mäkelä
We report on the properties of type II radio bursts observed by the Radio and Plasma Wave Experiment (WAVES) on board the Wind spacecraft over the past two solar cycles. We confirm…
Fermi, Wind, and SOHO Observations of Sustained Gamma-Ray Emission from the Sun
N. Gopalswamy, P. Makela, S. Yashiro +4
We report on the linear relationship between the durations of two types of electromagnetic emissions associated with shocks driven by coronal mass ejections: sustained gamma-ray em…
Long-term Solar Activity Studies using Microwave Imaging Observations and Prediction for Cycle 25
N. Gopalswamy, P. Makela, S. Yashiro +1
We use microwave imaging observations from the Nobeyama Radioheliograph at 17 GHz for long-term studies of solar activity. In particular, we use the polar and low-latitude brightne…
Energy Dependence of SEP Electron and Proton Onset Times
Hong Xie, Pertti Makela, Nat Gopalswamy +1
We study the large solar energetic particle (SEP) events that were detected by GOES in the 10 MeV energy channel during December 2006 to March 2014. We derive and compare solar…
