TL;DR: In this paper, the authors conducted approximately 2 years of GIC measurements in Hokkaido, Japan and found that GICs associated with substorms can be detected in Japan even at the solar minimum although intense GIC do occur mostly during geomagnetic storms.
Journal ArticleDOI
Solar Flare Prediction Model with Three Machine-Learning Algorithms Using Ultraviolet Brightening and Vector Magnetogram
TL;DR: In this paper, a machine learning-based approach was used to predict the maximum class of flares occurring in the following 24 hours, which is optimized to predict a large number of flares.
Journal ArticleDOI
Three‐dimensional MHD simulation of a loop‐like magnetic cloud in the solar wind
TL;DR: In this paper, a magnetic cloud ejected from the Sun is simulated as a part of a toroid and its evolution and propagation through interplanetary space are studied using three-dimensional magnetohydrodynamic self-consistent numerical simulations.
Journal ArticleDOI
Penetration of the convection and overshielding electric fields to the equatorial ionosphere during a quasiperiodic DP 2 geomagnetic fluctuation event
Takashi Kikuchi,Takashi Kikuchi,Yusuke Ebihara,Kumiko K. Hashimoto,Ryuho Kataoka,Tomoaki Hori,Shinichi Watari,Nozomu Nishitani +7 more
TL;DR: Huang et al. as discussed by the authors analyzed an equatorial DP 2 fluctuation event of 30 min duration, using magnetometer data, Super Dual Auroral Radar Network (SuperDARN) convection maps, and electric potentials calculated with the comprehensive ring current model.
