A powerful flare occurred on the Sun The flare lasted 29 minutes and was the most powerful since October 10, and was assigned to the M class (last second in the series A–. on-. C–. M–. X), reported in the Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences. The absolute size of the event is average. The outbreak stands out only against the background of the almost complete absence of such phenomena in recent times, scientists reassured. Ejected plasma clouds can theoretically reach Earth, but so far no clear consequences have been observed. Such events sometimes cause short-term disruptions in radio communications on the bright side of the Earth.
