Аннотация
In April 2017, the Event Horizon telescope received an image of a supermassive black hole in the Sagittarius A* source. This image consists of a ring-like structure that contains three areas with increased brightness (spots). If we assume that these spots are associated with flares near the event horizon of a black hole, then we can estimate its spin. Our estimate gives a value of the order of a ≈ 0.9.
