Is there a difference between the arrival of a CME and a meteor shower?The sky is swept with auroras. While auroras often cluster around the poles, their intensity allows them to travel to lower latitudes when a CME is strong enough. Even at regions far from the sun's polar caps, auroras have been observed.
Observers often claimed that meteor showers spread radially in different directions from a single centre in the sky. It is known that this is a kind of illusion associated with the effect of perspective. This effect of spreading from a point (centre) is caused by coming from afar, similar to the convergence of railroad tracks from one point. In fact, meteor showers, like railroad tracks, come parallel from a wide radiant. Everything is clear here.
However, why does a similar effect of spreading from one point as a center (in the sky), but far from the magnetic poles, occur when CMEs hit the Earth? After all, CMEs follow geomagnetic force lines and must enter through the magnetic poles.
How does the precipitation of CME’s particles in the atmosphere occur? Can they precipitate from one centre or should, going along the arcs of the lines of force, precipitate only along these arcs?
