Forbush Effect and the May 2024 Aurora in Georgia: Application of the HAVOK Method in Cosmic Ray Analysis

The Forbush decrease — a sudden and temporary reduction in the intensity of galactic cosmic rays — is one of the key physical processes driven by solar coronal mass ejections (CMEs) and dynamic variations of the interplanetary magnetic field.

Spatiotemporal Evolution of the 2022 March Interplanetary Coronal Mass Ejection Revealed by Multipoint Observations of Forbush Decreases

The Astrophysical Journal
Interplanetary coronal mass ejections (ICMEs) cause “Forbush decreases” (FDs), which are local decreases in background galactic cosmic rays (GCRs).

Cumulative effect of Forbush decreases in the heliospheric modulation during the present solar cycle

, 1985
A monthly Forbush decrease index (Fd-I) is generated and it is compared with the observed long term chnges in the cosmic ray intensity near earth at energies greater than or equal to 1 Gev over 1976-83. Significant correlation is observed between the two

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

Atmosphere
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 ...

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

Space 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 ...

Characteristics of Solar Flare Particle Increases during Recovery of Forbush Decreases with reference to 7 May 1978 Event [PDF]

, 1979
242-245Sudden increase of cosmic ray intensity registered mainly by ground based detectors is due to high energy particles of solar origin. These are generated on rare occasions during intense solar flares. Out of 30 ground level enhancements observed so

The effects of Forbush decreases on Antarctic climate variability: a re-assessment

, 2009
Abstract. In an attempt to test the validity of a relationship between Galactic cosmic rays (GCRs) and cloud cover, a range of past studies have performed composite analysis based around Forbush decrease (FD) events. These studies have produced a range of conflicting results, consequently reducing confidence in the existence of a GCR-cloud link.
