Field‐Aligned Currents and Auroral Precipitation During the Terrestrial Alfvén Wing State
Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract When sub‐Alfvénic (Alfvén Mach number MA< ${\mathrm{M}}_{A}< $1) plasmas impact Earth, Alfvén wings (AWs) develop. A Multiscale Atmosphere Geospace Environment simulation of the April 2023 storm, validated by Active Magnetosphere and Planetary Electrodynamics Response Experiment data, reveals the field‐aligned‐current (FAC) generation ...

H-alpha synoptic charts of solar activity during the first year of solar cycle 20, October 1964 - August 1965 [PDF]
Solar activity during the period October 28, 1964 through August 27, 1965 is presented in the form of charts for each solar rotation constructed from observations made with the chromospheric H-alpha spectra line.

Re-evaluation of cosmic ray cutoff terminology [PDF]
The study of cosmic ray access to locations inside the geomagnetic field has evolved in a manner that has led to some misunderstanding and misapplication of the terminology originally developed to describe particle access.

Numerical simulation of helical-vortex effects in Rayleigh-Bénard convection [PDF]
Nonlinear Processes in Geophysics, 2006 A numerical approach is substantiated for searching for the large-scale alpha-like instability in thermoconvective turbulence. The main idea of the search strategy is the application of a forcing function which can have a physical interpretation.
