Fractal Dimension Analysis of Earth Magnetic Field during 26 August 2018 Geomagnetic Storm
We analyse the fractal nature of geomagnetic field northward and eastward horizontal components with 1 min resolution measured by the four stations Belsk, Hel, Sodankylä and Hornsund during the period of 22 August–1 September, when the 26 August 2018 geomagnetic storm appeared. To reveal and to quan...
