The alarm began this Saturday, when experts detected that the active sunspot erupted, producing a strong solar flare and an ejection of its mass. The effects will be noticeable late on Monday and could persist through Tuesday.
According to the National Oceanic and Atmospheric Administration of the United States (NOAA, for its acronym in English), this Monday a solar storm could reach Earth, a phenomenon that, depending on the severity with which it occurs, has the possibility of affecting the entire electrical network and internet wiring.
The effects of this phenomenon would be noticeable on Monday at the last minute and could persist through Tuesday.
The CME is "a giant cloud of solar plasma soaked with magnetic field lines that is often ejected from the Sun during strong long-duration solar flares and filament flares," explained on the Meteored site.
According to NOAA specialists, the CME could cause geomagnetic storms, which would be reflected as northern lights in countries such as Australia, Scotland, southern Sweden and the northern states of the United States.
The NOAA alert also highlighted that the geomagnetic storm can cause fluctuations in the electrical network with voltage alarms at higher latitudes, since in those areas the Earth is more exposed.
In addition, satellites could be affected and show "orientation irregularities" so they would have to be redirected from the ground controls, as well as any object in low Earth orbit that experiences greater resistance.
Radiation from the flare ionized the upper part of Earth's atmosphere. This, in turn, caused a shortwave radio blackout over the Indian Ocean. Airmen, radio amateurs and ships at sea may have noticed strange propagation effects at frequencies below 25 MHz, ”Meteored reported.
