Spectral analysis of the Forbush decrease of 13 July 1982 [PDF]

open access: yes
The maximum entropy method has been applied in the spectral analysis of high-energy cosmic-ray intensity during the large Forbush event of July 13, 1982.

Forbush Decrease Data with a Simple Model

open access: yes, 2006
On October 28, 2003 an earthward-directed coronal mass ejection (CME) was observed from SOHO/LASCO imagery in conjunction with an X17 solar flare. The CME, traveling at nearly 2000 km/s, impacted the Earth on October 29, 2003 causing ground-based particle detectors to register a counting rate drop known as a Forbush decrease.

Multipoint Observations and Modeling of the 2021 November 4 Forbush Decrease Using Solar Orbiter, CSES-01, and Ground-based Neutron Monitor Data

open access: yesThe Astrophysical Journal
During their propagation in the heliosphere, interplanetary coronal mass ejections (ICMEs) interact with galactic cosmic ray (GCR) particles, modifying their spectrum and driving anisotropies.

Cosmic ray modulation by high-speed solar wind fluxes [PDF]

open access: yes
Cosmic ray intensity variations connected with recurrent high-speed fluxes (HSF) of solar wind are investigated. The increase of intensity before the Earth gets into a HSF, north-south anisotropy and diurnal variation of cosmic rays inside a HSF as well ...

Solar Latitudinal Distribution of Solar Flares around the Sun and Their Association with Forbush Decreases during the Period of 1986 to 2003 [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2005
Solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23.

The intensity recovery of Forbush-type decreases as a function of heliocentric distance and its relationship to the 11-year variation [PDF]

open access: yes
Recent data indicating that the solar modulation effects are propagated outward in the heliospheric cavity suggest that the 11-year cosmic ray modulation can best be described by a dynamic time dependent model.

Cosmic ray modulation and turbulent interaction regions near 11 AU [PDF]

open access: yes
When Voyager 2 was near 11 AU, the counting rate of nuclei approx 75 MeV/nucleon decreased during the interval from July, 1982 to November, 1982, and it increased thereafter until August, 1983.

Observation of the Forbush Decrease on 2024 May 10, Using the ALPAQUITA Air-shower Array at the 70–1000 GV Rigidity Range

open access: yesThe Astrophysical Journal
The Andes Large area PArticle detector for Cosmic ray physics and Astronomy is a new air-shower array experiment under construction in the Bolivian Andes, and its prototype ALPAQUITA surface array has been operating since 2023 April.
