TL;DR: The PWING project as mentioned in this paper has been carried out since April 2016 to provide the global distribution and quantitative evaluation of the dynamical variation of these plasmas and waves in the inner magnetosphere.
Journal ArticleDOI
Magnetic conjugacy of northern and southern auroral beads
TL;DR: In this paper, the authors used simultaneous ground-based, all-sky camera observations from a geomagnetically conjugate Iceland-Syowa Station pair to demonstrate that the auroral beads, whose wavelength is ∼30-50 km, evolve synchronously in the northern and southern hemispheres and have remarkable interhemispheric similarities.

TL;DR: In this article, the effect of a flare-associated interplanetary shock and the disturbed region behind it (characterized by enhancement in velocity and magnetic field, and decrease in mean free path) on the density and anisotropy of cosmic rays in the heliosphere is estimated.
