Global analysis of the extended cosmic-ray decreases observed with world-wide networks of neutron monitors and muon detectors; temporal variation of the rigidity spectrum and its implication

K. Munakata, Y. Hayashi, M. Kozai +20

This paper presents the global analysis of two extended decreases of the galactic cosmic ray intensity observed by world-wide networks of ground-based detectors in 2012. This analy…

Coronal mass ejection deformation at 0.1 au observed by WISPR

Carlos R. Braga, Angelos Vourlidas, Paulett C. Liewer +3

Although coronal mass ejections (CMEs) resembling flux ropes generally expand self-similarly, deformations along their fronts have been reported in observations and simulations. We…

Large amplitude bidirectional anisotropy of cosmic-ray intensity observed with world-wide networks of ground-based neutron monitors and muon detectors in November, 2021

K. Munakata, M. Kozai, C. Kato +24

We analyze the cosmic-ray variations during a significant Forbush decrease observed with world-wide networks of ground-based neutron monitors and muon detectors during November 3-5…

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…

Coronal mass ejections observed by heliospheric imagers at 0.2 and 1 au: the events on April 1 and 2, 2019

Carlos Roberto Braga, Angelos Vourlidas

Context. We study two coronal mass ejections (CMEs) observed between April 1-2, 2019 by both the inner Wide-Field Imager for Parker Solar Probe (WISPR-I) and the inner heliospheric…
