Diffusion processes of cosmic rays with energies between 2 and 20 GV during Forbush decreases: The diurnal effect

, 1972
A study of the morphology of the diurnal variation of the cosmic-ray intensity during the Forbush decreases in the periods 15 October 1965 30 June 1966 and 21 January 1967-17 December 1968 is presented in this article.

Precursor Effects in Different Cases of Forbush Decreases

, 2012
Over the last few years, the pre-decreases or pre-increases of the cosmic-ray intensity observed before a Forbush decrease, called the precursor effect and registered by the worldwide neutron monitor network, have been investigated for different cases of

Effects of the May 10, 2024 solar storm on the South Atlantic Anomaly: a case study in Bolivia

Earth, Planets and Space
We analyzed the strongest geomagnetic storm of the last two decades, which occurred on May 10, 2024, focusing on satellite plasma data, magnetic field variations recorded at the Villa Remedios Magnetic Observatory, and neutron data from the 12-NM64 ...

Multi-particle analysis of the december 13th 2006 forbush decrease with PAMELA experiment

, 2013
In this paper we present PAMELA multi-particle observation of the Forbush decrease (FD) following the December 13th 2006 solar particle event. The FD is the sudden decrease of the galactic cosmic ray flux due to the transit of a Coronal Mass Ejection ...

Cosmic Ray Intensity Decrease of 23 September, 1966

, 1971
Earlier studies have interpreted the Forbush decrease of 23 September 1966 in terms of two phases; an initial predecrease and a later worldwide decrease.

Effects of Geomagnetic Cutoff Rigidity Variations during Forbush Decreases

Forbush decreases (FDs) are short-term reductions in galactic cosmic ray flux caused by interplanetary disturbances. During some interplanetary coronal mass ejection (ICME) events, neutron monitor (NM) data also contain variations produced by geomagnetic storms.
