Analysis of the Geomagnetic Storm from March 23–24, 2024, which had a Strong Impact on the Earth

Geomagnetic storms have a negative impact on energy infrastructures, air transport, communications and the satellite missions. By increasing the intensity of the induced geomagnetic currents, damage and even significant destruction can occur in these vital areas. The analysis of geomagnetic storms can be done by statistical, spectral and wavelet methods, corroborated with the astrophysical observation data provided by the most important specialized sites. The example presented in the paper refers to the event from March 23–24, 2024. This event was studied by these methods and wavelet coherence for many planetary observatories in the INTERMAGNET network. This storm, which affected the entire planet, had the greatest intensity in the northern latitudes, where spectacular aurora borealis were noted. Very good correlations (close to 1) were noted between geomagnetic observatories located at latitudes and longitudes all over the Earth.
