At 00:25 Moscow time, a flare of M4.6 power occurred on the star in sunspot group No. 3182. IN
As AstroAlert notes, with a high probability, this ejection will "touch" the Earth. This means that a geomagnetic storm is expected on the planet. Estimated date - January 19 inclusive.
Also, according to spaceweather.com, the expected class of geomagnetic storms is G1. This is a small power, but the appearance of aurora is possible. They are formed due to flows of high-energy charged particles. Previously, they were reported as a result of a substorm on the night from Sunday to Monday.
Solar flares depending on powerX-ray radiation is divided into five classes: A, B, C, M and X. The minimum class A0.0 corresponds to a radiation power in Earth's orbit of 10 nanowatts per square meter. When moving to the next letter, the power increases 10 times.
A coronal mass ejection (CME) is aa giant cloud of solar plasma riddled with magnetic field lines that spreads away from the Sun during intense, long-lasting solar flares and filament eruptions.
