A statistical comparison of hot-ion properties at geosynchronous orbit during intense and moderate geomagnetic storms at solar maximum and minimum. [PDF]

open access: yes, 2006
Hot-ion measurements at geosynchronous orbit from the Los Alamos Magnetospheric Plasma Analyzer (MPA) instrument during geomagnetic storms at solar maximum (July 1999–June 2002) and at solar minimum (July 1994–June 1997) are collected, categorized, and ...

Variation of Magnetic Field (By , Bz) Polarity and Statistical Analysis of Solar Wind Parameters during the Magnetic Storm Period [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2011
It is generally believed that the occurrence of a magnetic storm depends upon the solar wind conditions, particularly the southward interplanetary magnetic field (IMF) component. To understand the relationship between solar wind parameters and magnetic

Seasonal variations in the occurrence of geomagnetic storms [PDF]

open access: yesAnnales Geophysicae, 1996
Seasonal variations in the onset of magnetic storms are investigated. For the purposes of this study storms have been defined as events in which Dst falls below –50 nT for at least four consecutive hours.

Differences in the response to CME and CIR drivers of geomagnetic disturbances

open access: yesSolar-Terrestrial Physics, 2023
Utilizing 1-minute resolution data on the geomagnetic indices SYM-H, AE, solar wind parameters (velocity Vsw and density Np), and z-component Bz of the interplanetary magnetic field (IMF) during solar cycles 23 and 24, we have statistically analyzed the ...

Mercury's magnetospheric substorm and storm

open access: yes地球与行星物理论评, 2022
Magnetospheric substorms and magnetic storms are explosive energy storage and release processes occurring during the interactions between the solar wind and planetary magnetospheres. They are accompanied by complex plasma dynamics processes and they have

ANALYSIS OF THE MAGNETIC STORMS CATALOG FOR MONITORING RADIO SOURCE FLUXE DATA WITH THE URAN-4 RADIO TELESCOPE IN THE ODESA MAGNETIC ANOMALY ZONE [PDF]

open access: yesRadio Physics and Radio Astronomy, 2020
Purpose: Compilation of a digital catalog of magnetic storms in the Odesa magnetic anomaly zone in order to find the reasons for possible changes in the radiation fluxes of cosmic radio sources, according to observations at the URAN-4 radio telescope.

Relationship of the ASY-H index with interplanetary medium parameters and auroral activity in magnetic storm main phases during CIR and ICME events

open access: yesSolar-Terrestrial Physics, 2020
In this study, we examine the relationship of the ASY-H index characterizing the partial ring current intensity with interplanetary medium parameters and auroral activity during the main phase of magnetic storms, induced by the solar wind (SW) of ...

Association of radiation belt electron enhancements with earthward penetration of Pc5 ULF waves: a case study of intense 2001 magnetic storms [PDF]

open access: yesAnnales Geophysicae, 2015
Geospace magnetic storms, driven by the solar wind, are associated with increases or decreases in the fluxes of relativistic electrons in the outer radiation belt.

Magnetic Signatures of Ionospheric Disturbance Dynamo for CME and HSSWs Generated Storms

open access: yesSpace Weather, 2021
Ionospheric disturbance dynamo is one of the main processes that causes perturbations in the upper atmosphere during a magnetic storm. We present a new method, based on the least square fitting, for estimation of the magnetic signatures associated with ...

Cosmic rays as an indicator of the geoeffectiveness of magnetic clouds [PDF]

open access: yesE3S Web of Conferences, 2019
Geomagnetic storms are initiated by organized magnetic structures of the solar wind. The intensity of magnetic storms is determined by the product of the southward component of the magnetic field and the time interval, during which the structure is ...
