The geomagnetic response to the X-class solar flares of September 2017 Ghent University
This study analyzes the variations in the levels of the Earth's magnetic field and its fluctuations in the range of periods of 1–1000 s that accompanied X-class solar flare on 6, 7, and 10 September 2017. Variations of the main Geomagnetic field (GMF) and the fluctuations in the range of periods 1–1000 s were measured by the magnetometer (located at 49.93°N, 36.95°E). The X9.3-class solar flare (SF) on 6 September 2017 induced substantial ...
