The record of the magnetic storm on 15 May 1921 in Stará Ďala (present-day Hurbanovo) and its compliance with the global picture of this extreme event [PDF]

open access: yesAnnales Geophysicae, 2023
This paper deals with the most intense magnetic storm of the 20th century, which took place on 13–15 May 1921. Part of this storm was observed in the magnetic declination and vertical intensity at Stará Ďala, currently known as Hurbanovo.

Case studies of space weather events from their launching on the Sun to their impacts on power systems on the Earth [PDF]

open access: yesAnnales Geophysicae, 2002
Active geomagnetic conditions on 12–13, 15–16, and 22–23 September 1999 resulted in geomagnetically induced currents (GIC) measurable in power systems in Canada and the United States.

Modelling of geomagnetic induction in pipelines [PDF]

open access: yesAnnales Geophysicae, 2002
Geomagnetic field variations induce telluric currents in pipelines, which modify the electrochemical conditions at the pipe/soil interface, possibly contributing to corrosion of the pipeline steel.

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.

Empirically modelled Pc3 activity based on solar wind parameters [PDF]

open access: yesAnnales Geophysicae, 2010
It is known that under certain solar wind (SW)/interplanetary magnetic field (IMF) conditions (e.g. high SW speed, low cone angle) the occurrence of ground-level Pc3–4 pulsations is more likely.

The presence of large sunspots near the central solar meridian at the times of major geomagnetic storms [PDF]

open access: yesAnnales Geophysicae, 2009
A further study is made of the validity of a technique developed by the authors to identify historical occurrences of intense geomagnetic storms, which is based on finding approximately coincident observations of sunspots and aurorae recorded in East ...
