There is not only the bad weather in this post-August 15th, but also the solar storms. In fact in the next few hours high-energy particles from the Sun they will hurl themselves against the Earth causing a geomagnetic storm class G3i.e. classified as loud.
In recent days there has been a large coronal mass ejection, which has generated magnetic “turbulence” that will hit our planet today, Thursday August 18and tomorrow, Friday 19 August. Despite being classified as third level, in concrete terms the solar storm should still have a little or no impact. For this reason no major inconveniences are expected: at most there could be small fluctuations in the electricity network, satellite irregularities and disturbances in radio and GPS signals.
As is well known, however, this is not a rare phenomenon: the most recent precedent dates back to first days of Augustwhen a coronal hole in the southern hemisphere of the Sun it induced a magnetic storm, but of a smaller size.
A fusion of solar storms
According to when observed by scientists, on August 14 last there was an eruption of plasma from the solar corona, recorded by various observatories and – in particular – by the Space Weather Prediction Center (Swpc) of the National Oceanic and Atmospheric Administration (Noaa), which has highlighted a ‘explosion of a superficial sunspot. This then caused the generation of an extraordinary magnetic field, which is now heading towards Earth. The following day, August 15, a second coronal mass was ejected from the Sun, again directed towards the Earth and created by the collapse of a gigantic magnetic filament. When such events occur, it can happen that the waves directed towards our planet interact with the Earth’s magnetic fieldcreating problems and disservices of various kinds.
The event expected for these hours, however, has a particularity. Referring to the forecasts produced by the Noa, the two eruptions will merge together, forming in a single storm that will interfere with the Earth’s magnetic field. This phenomenon occurs when a rapidly moving solar eruption incorporates a previous eruption: from the union of the charged particles a wave front of great intensity is formed which, once it reaches the Earth, typically determines a geomagnetic storm of intensity. medium-high.
It will not be a record storm, on the contrary
Magnetic storms are classified from G1 to G5 based on their power: those G3, as anticipated, are defined strong and are capable of intermittent problems, especially for low frequency and satellite navigation. The most powerful solar storms are able to cause much more serious damage: significantly interfere with the magnetic field of our planet, drop satellites directly on the ground and even – potentially – paralyze the internet.
The most powerful solar storm in recent history dates back to 1859, when the same energy was released from the Sun as about 10 billion 1-megaton atomic bombs. The powerful stream of particles, after crashing into the Earth, has destroyed the telegraph systems around the world and caused it displacement of the Northern Lights, making them visible from the Caribbean. An event of the same magnitude today would cause enormous damage and widespread blackouts around the world, but the solar storm of these days has nothing to do with all this and will not cause particularly significant damage. In short, at least on this front you can rest assured.
