Radial Evolution of the April 2020 Stealth Coronal Mass Ejection between 0.8 and 1 AU -- A Comparison of Forbush Decreases at Solar Orbiter and Earth
Johan L. Freiherr von Forstner, Mateja Dumbović, Christian Möstl +40
Aims. We present observations of the first coronal mass ejection (CME) observed at the Solar Orbiter spacecraft on April 19, 2020, and the associated Forbush decrease (FD) measured…
Peculiar solar sources and geospace disturbances on 20-26 August 2018
A. A. Abunin, M. A. Abunina, A. V. Belov +1
On the approach to minimum of Solar Cycle 24, on 26 August 2018, an unexpectedly strong geomagnetic storm (GMS) suddenly occurred. Its Dst index reached -174 nT, that is the third…
Relationship between the Magnetic Flux of Solar Eruptions and the Ap Index of Geomagnetic Storms
I. M. Chertok, M. A. Abunina, A. A. Abunin +2
Solar coronal mass ejections (CMEs) are main drivers of the most powerful non-recurrent geomagnetic storms. In the extreme-ultraviolet range, CMEs are accompanied by bright post-er…
