An eruption of dark plasma on the Sun could cause a radio blackout on Earth.
The likelihood of such events increases at least until Friday of this week.
So-called cold solar flares have up to a 60 percent chance of causing radio communications disruption in the coming days, the Daily Mail reports.
According to the US National Oceanic and Atmospheric Administration, flares can affect radio, aviation and satellite communications.
Experts predict that the consequences of the solar dark plasma flares can be expected by at least Friday.
The probability of radio interference on Earth due to flares is estimated to reach 60 percent.
Astrophysicists are increasingly interested in the phenomenon of cold solar flares on the Sun.
They turned out to have no less microwave radiation than warm ones.
The peculiarity of these flares is that they produce higher peak frequencies of gyrosynchrotron radiation, which is responsible for destructive radio emissions.
