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 ...

A New Installation for Geomagnetic Field Monitoring at Talos Dome, a Remote Antarctic Site Away from Permanent Observatories

open access: yesRemote Sensing, 2023
An automatic geomagnetic station for monitoring the Earth’s magnetic field variations was installed in December 2020 at Talos Dome, a remote site on the Antarctic Plateau, about 300 km away from the permanent geomagnetic observatory at Mario Zucchelli ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Report on the magnetic survey in Slovakia for the 2014.5 epoch

open access: yesContributions to Geophysics and Geodesy, 2016
The models of the distribution of the elements of the geomagnetic field must be updated regularly. For this purpose geomagnetic measurements have to be carried out repeatedly at geomagnetic observatories as well as at temporary observation points.

Variations in the magnetic declination at mid-latitude European stations during the Carrington-like event on 29 October 2003 [PDF]

open access: yesAnnales Geophysicae
Based on the declination observed at mid-latitude European stations (geomagnetic latitudes 34–58° N), we studied the current system that is a candidate for the cause of the sharp drop in horizontal intensity (H) of the geomagnetic field that occurred in ...

COMPARATIVE ANALYSIS OF GEOMAGNETIC DISTURBANCES IN THE ODESSA MAGNETIC ANOMALY AREA IN THE 24TH SOLAR ACTIVITY CYCLE

open access: yesRadio Physics and Radio Astronomy, 2019
Purpose: The main oscillation periods of the geomagnetic field perturbation level in the Odesa magnetic anomaly area are studied by the data observed at the “Odesa” geomagnetic observatory within the 24th solar activity cycle.

Datasets of the solar quiet (Sq) and solar disturbed (SD) variations of the geomagnetic field from the mid latitudinal Magnetic Observatory of Coimbra (Portugal) obtained by different methods

open access: yesData in Brief, 2021
The datasets of daily variations is obtained from the geomagnetic field raw observations at the Coimbra Magnetic Observatory (COI, Portugal). The data set was obtained for the 01.01.2007-31.12.2017 time interval and covers almost the entire solar cycle ...
