Diagnostics of the sources of geomagnetic variations for the superstorm of October 10—11, 2024 according to the Ukrainian geomagnetic observatories’ data
The paper analyses magnetospheric-ionospheric sources of geomagnetic variations for the superstorm of October 10—11, 2024. This event occurred at the maximum of the 25th Wolf cycle and the beginning of a 100-year cycle of geomagnetic activity. During this period, superstorms similar to the storms of...

This event occurred at the maximum of the 25th Wolf cycle and the beginning of a 100-year cycle of geomagnetic activity. During this period, superstorms similar to the storms of October—November 2003 will occur.
To analyze the sources of variations, 1-minute values of Ukrainian geomagnetic observatories were used. The sources of geomagnetic variations were identified based on the indices of geomagnetic activity and model calculations. The influence of magnetospheric sources and auroral ionospheric electric currents in the middle latitudes variations was diagnosed. The contribution of eachsources calculated. |
