Spots of incredible size have been recorded on the Sun. They are visible even without a telescope, according to Sergei Nazarov, a researcher at the Crimean Astrophysical Observatory (CrAO).
They can be observed even without telescopes, using anything as a filter, such as smoked glass or X-ray film. You can make a projection onto a sheet of paper through binoculars, and if the atmosphere is dense, it will be visible at sunset.
Sunspots are areas on its surface that are cooler than the rest of the star. These formations change in size throughout their lives and arise as a result of the interaction of magnetic fields with solar matter. When the substance cools, it becomes visually similar to a spot.
This indicates that the magnetic fields on the Sun are very strong, and because of them, flares can occur that can affect us. If such a flare occurs, powerful auroras will be repeated, like those we observed in May last year. This could happen at any second.
According to the scientist, auroras usually appear a day or two after powerful solar flares. In this regard, Crimean astrophysicists are now especially carefully monitoring the activity of our star in order to better understand its impact on the Earth and atmospheric phenomena.
