The 17 March 2015 storm: the associated magnetic flux rope structure and the storm development
Katsuhide Marubashi,Katsuhide Marubashi,Kyung-Suk Cho,Rok-Soon Kim,Sujin Kim,Sung-Hong Park,Hiromitsu Ishibashi +6 more
TL;DR: In this paper, the authors determined the magnetic cloud (MC) structure associated with the 17 March 2015 storm and gained an insight into how the storm developed responding to the solar wind conditions by fitting to both cylindrical and toroidal flux rope models.
Journal ArticleDOI
Interplanetary Magnetic Flux Ropes as Agents Connecting Solar Eruptions and Geomagnetic Activities
TL;DR: In this article, the authors investigated the solar wind structure for 11 cases that were selected for the campaign study promoted by the International Study of Earth-affecting Solar Transients (ISEST) MiniMax24 Working Group 4.
Journal ArticleDOI

Journal ArticleDOI
Structure of interplanetary magnetic cloud on April 16, 1999 and its origin estimated by fitting the torus‐shaped flux rope model
TL;DR: In this article, the authors examined the relationship between interplanetary magnetic cloud observed by the ACE satellite on April 16, 1999 and its solar origin, which is consistent with previous studies about magnetic clouds and their solar origins, although corresponding solar surface phenomena occurred near the central meridian.
