All over the northern hemisphere, from Europe to North America, people could see the spectacular red light display, which has already been called the “Holy Grail of the Northern Lights.” Of course, the show also caught the cameras’ lenses.

lots of photos

Red auroras are extremely rare compared to the more common green auroras. Seeing them with the naked eye is a remarkable thing, especially this far south, as far as France and Kansas.

The color of the radiation depends on the gas with which the solar radiation reacts. A strong enough coronal ejection can break the protection of the magnetic field. It then hits the atmosphere, tearing off its outer layers. Depending on how deep the emission reaches the atmosphere and how far it is locally displaced from the north pole, this will be a glow, as each element emits light of specific wavelengths and prevails at its height above the planet’s surface.

According to the website EarthSky, which writes about space and atmospheric events, the flare was triggered by a strong (though not extreme) solar storm accompanied by a coronal mass ejection. Scientists don’t yet know which epidemics cause this. During the day before the impact, our star emitted 18 flares; 13 of these occurred in just one small sunspot (AR3445). The most likely candidate so far is the flare produced by another dot, AR3443, which produces only one emission but is the largest of the eighteen emissions. It probably also influenced radio work in South America.

Green auroras are the most common on Earth. They also result from the emission of light by individual oxygen atoms held high in the atmosphere. Where high-speed electron showers have enough energy to penetrate deeper into the atmosphere, they can cause nitrogen atoms and ions to emit blue and pink colors, mixing to form a soft purple at the edges.

Although scientists were able to predict this solar storm on September 24, the impact turned out to be stronger than expected. The solar flare immediately caused a severe geomagnetic storm over Europe, causing bright green and red lights to appear in the skies over Scotland, Iceland and the Netherlands.

The light show then flew across the Atlantic Ocean to North America. Residents of the southern states of Kansas and Nebraska witnessed a rare event.
