It refers to a specific phenomenon observed in the aurora borealis, where distinct bands or ribbons of color appear to be drawn out from a central point or along a specific direction. This visual effect is a result of the complex interactions between charged particles from the sun and the Earth's magnetic field and atmosphere.
When solar wind particles, primarily electrons and protons, collide with gases in the upper atmosphere, they
The specific colors observed in the aurora depend on the type of gas particles involved and the
