A quiescent photo voltaic wind flowing past Earth's magnetosphere steadily interacts with it and will the two inject photo voltaic wind particles straight onto the geomagnetic industry strains that happen to be 'open up', rather than being 'shut' in the opposite hemisphere and supply diffusion through the bow shock. It can also trigger particles by now trapped inside the radiation belts to precipitate into the ambiance. The moment particles are shed for the atmosphere within the radiation belts, underneath peaceful problems, new ones switch them only gradually, and the decline-cone gets depleted. Within the magnetotail, nevertheless, particle trajectories look constantly to reshuffle, in all probability once the particles cross the extremely weak magnetic field close to the equator.
So then you believe it’s smoke… but that doesn’t look suitable possibly.

Eco-friendly: At decreased altitudes, the more Regular collisions suppress the 630 nm (pink) method: alternatively the 557.7 nm emission (inexperienced) dominates. A reasonably higher focus of atomic oxygen and better eye sensitivity in eco-friendly make eco-friendly auroras the commonest. The excited molecular nitrogen (atomic nitrogen staying rare a result of the superior steadiness from the N2 molecule) plays a role below, as it may possibly transfer Strength by collision to an oxygen atom, which then radiates it absent on the environmentally friendly wavelength.
