Is this cartoon describing a flare, a CME, or a jet?
The Archivist would regard these as a brightening, a perpendicular plasma flow,
or a parallel flow.
Observationally this distinction is based on the image morphology, which is a bit
fuzzy given that we cannot readily distinguish a streamer ray (which
underlies the traditional "blow-out" CME with its three parts),
and a pseudo-streamer (which is unipolar).
Of course at the level of the real physics, all of these phenomena, including
both kinds of flows, can be happening more or less simultaneously.
Here though the artist has called our attention to the fact that a jet ("narrow CME"
being a poor name for the process) may not involve much perpendicular plasma flow.
See the revolutionary mini-filament idea
for further confusion here.
