Effect of Finite Larmor Radius on the Cosmic Ray Penetration into an Interplanetary Magnetic Flux Rope

open access: yes, 2010
We discuss a mechanism for cosmic ray penetration into an interplanetary magnetic flux rope, particularly the effect of the finite Larmor radius and magnetic field irregularities.

First Major Eruption of Solar Cycle 25: Impacts of the 3 July 2021 X1.59 Solar Flare on the Ionosphere and Primary Cosmic Rays

open access: yesAtmosphere
The X1.59 solar flare on 3 July 2021, was the first X-class flare of Solar Cycle 25 and the first since the X-class flare on 10 September 2017. This event was notable for producing a rare geomagnetic crochet, a temporary and localized perturbation in ...

Tracking and Validating ICMEs Propagating Toward Mars Using STEREO Heliospheric Imagers Combined With Forbush Decreases Detected by MSL/RAD

open access: yes, 2019
The Radiation Assessment Detector (RAD) instrument onboard the Mars Science Laboratory (MSL) mission's Curiosity rover has been measuring galactic cosmic rays (GCR) as well as solar energetic particles (SEP) on the surface of Mars for more than 6 years ...

The Magnetosphere‐Ionosphere‐Ground Responses to the May 2024 Super Solar Storm

open access: yesSpace Weather
Earth suffered the attack of the strongest geomagnetic storm in the last 20 years (Kp = 9, Dst∼ −400 nT) occurred on 11 May 2024. Taking advantage of the LEO multi‐parameter CSES satellite (launched in 2018) with a large inclination angle 97°, with the ...

Forcing of Climate Variations by Mev-gev Particles [PDF]

open access: yes, 1990
Changes in ionization production in the lower stratosphere by a few percent during Forbush decreases have been shown to correlate well with changes in winter tropospheric dynamics by a similar relatively small amount.

Astroparticle Physics at Eastern Colombia

open access: yes, 2015
We present the emerging panorama of Astroparticle Physics at Eastern Colombia, and describe several ongoing projects, most of them related to the Latin American Giant Observatory (LAGO) Project.

Forbush-effects and atmospheric pressure dynamics at high-altitude Tien Shan station

open access: yesJournal of Physics: Conference Series, 2013
We present atmospheric pressure dynamics studies at the high-altitude Tien Shan station (3340 m above sea level) during 23rd cycle of solar activity after Forbush-effects. It is established that 80 % of Forbush effects with delay 1 ? 3 days are accompanied with steady depression of atmospheric pressure irrespective of geomagnetic field conditions.

Electron density profiles in the background of LF absorption during Forbush-decrease and PSE [PDF]

open access: yes
Based on the simulation of different Forbush decrease and particle precipitation effects in the D region, electron density profiles in the mid-latitudes the ionospheric absorption of low frequency (LF) radio waves was determined.

Superposed epoch study of ICME sub-structures near Earth and their effects on galactic cosmic rays

open access: yes, 2016
Interplanetary coronal mass ejections (ICMEs) are the interplanetary manifestations of solar eruptions. The overtaken solar wind forms a sheath of compressed plasma at the front of ICMEs.
