The Sun sends us not only heat and light, but also a lot of other energy and small particles. The energy is released when suspended particles separated from the Sun — the solar wind — collide with particles of the Earth's atmosphere. That's when we see a colorful glowing halo — an aurora.
It can be of different colors, depending on the altitude and the kind of atoms involved. Auroras usually appear only in the lower polar regions.
Recently, there was a powerful flare on the sun, the particles of which were enough to disrupt the Earth's magnetic field - so much so that the aurora even reached the southern latitudes. As a result, the aurora borealis was visible in almost the entire country, and even in the south of the country, which is a particularly rare occurrence.
