Suprathermal particle addition to solar wind pressure: possible influence on magnetospheric transmissivity of low energy cosmic rays?

TL;DR

This paper investigates how suprathermal solar particles, which increase solar wind pressure during high activity, may affect the Earth's magnetosphere's ability to transmit low-energy cosmic rays, based on a recent solar event.

Contribution

It provides an estimation of the impact of suprathermal particles on magnetospheric transmissivity during solar activity, highlighting a potential influence on cosmic ray shielding.

Findings

Suprathermal particles increase solar wind pressure during high activity.

Elevated pressure may alter magnetospheric transmissivity.

Analysis based on a recent solar event.

Abstract

Energetic (suprathermal) solar particles, accelerated in the interplanetary medium, contribute to the solar wind pressure, in particular during high solar activity periods. We estimated the effect of the increase of solar wind pressure due to suprathermal particles on magnetospheric transmissivity of galactic cosmic rays in the case of one recent solar event.
