Energetic Electron Precipitation Occurrence Rates Determined Using the Syowa East SuperDARN Radar

Emma C. Bland, Noora Partamies, Erkka Heino +2

We demonstrate that the Super Dual Auroral Radar Network (SuperDARN) radar at Syowa station, Antarctica, can be used to detect high frequency radio wave attenuation in the D region…

Comparative study of electric currents and energetic particle fluxes in a solar flare and Earth magnetospheric substorm

Anton Artemyev, Ivan Zimovets, Ivan Sharykin +20

Magnetic field-line reconnection is a universal plasma process responsible for the conversion of magnetic field energy to the plasma heating and charged particle acceleration. Sola…

New cosmic ray observations at Syowa Station in the Antarctic for space weather study

C. Kato, W. Kihara, Y. Ko +9

Muon detectors and neutron monitors were recently installed at Syowa Station, in the Antarctic, to observe different types of secondary particles resulting from cosmic ray interact…

A Peculiar ICME Event in August 2018 Observed with the Global Muon Detector Network

W. Kihara, K. Munakata, C. Kato +20

We demonstrate that global observations of high-energy cosmic rays contribute to understanding unique characteristics of a large-scale magnetic flux rope causing a magnetic storm i…

Eastward-expanding auroral surges observed in the post-midnight sector during a multiple-onset substorm

Yoshimasa Tanaka, Yasunobu Ogawa, Akira Kadokura +9

We present three eastward-expanding auroral surge (EEAS) events that were observed intermittently at intervals of about 15 min in the post-midnight sector (01:55-02:40 MLT) by all-…

Vortices at the magnetic equator generated by hybrid Alfven resonant waves

Yasutaka Hiraki

We performed three-dimensional magnetohydrodynamic simulations of shear Alfven waves in a full field line system with magnetosphere-ionosphere coupling and plasma non-uniformities.…

Auroral vortex street formed by the magnetosphere-ionosphere coupling instability

Yasutaka Hiraki

By performing three-dimensional nonlinear MHD simulations including Alfven eigenmode perturbations most unstable to the ionospheric feedback effects, we reproduced the auroral vort…
