Cosmic Ray Muons and Neutrons data at Syowa Station in the Antarctic reveals structure of Coronal Mass Ejections affect on Earth

The research group including Shinshu University and National Institute of Polar Research has been continuing simultaneous observations with muon detectors and neutron monitors at Syowa Station in the Antarctic since February 2018. Small fluctuation in cosmic ray count was found in August 2018, and researchers concluded it was caused by coronal mass ejection (CME). By analyzing the data with the global muon detector network and the world-wide network of neutron monitors, they showed the internal structure of the CME when it arrives on Earth.

This analysis was performed by Wataru Kihara, Graduate School of Science and Technology, who is a laboratory member of Prof. Kato, Faculty of Science at Shinshu University.
