A Simultaneous Forbush Decrease Associated with an Earthward Coronal Mass Ejection Observed by STEREO

, 2012
The intensity–time profile of Forbush decrease (FD) events observed by neutron monitors (NMs) looks like that of a geomagnetic storm as defined by the Dst index. Oh, Yi, and Kim (J. Geophys. Res. 113, A01103, 2008) and Oh and Yi (J. Geophys. Res.

Identification of Coronal Mass Ejection–Driven Shocks Based on Numerical Simulation and Deep Learning

The Astrophysical Journal
Coronal mass ejections (CMEs) are eruptions originating from the solar corona, usually carrying a large amount of fast-flowing plasma into interplanetary space, accompanied by an enhanced magnetic field.
