There geomagnetic storm in progress from the evening of April 15th It is still increasing its strength compared to the initial forecasts: it could now reach the G4 classwhich indicates an event of severe intensityon a staircase ranging from G1 A G5. «For many hours a geomagnetic storm has been underway whose intensity oscillates between the G2 class And G3and an intensification is expected to G4»He says to Ansa Mauro Messerottiprofessor of Space meteorology atUniversity of Trieste.
According to the data provided by German Center Helmholtz for Geosciences (GFZ)in fact, have occurred New peaks of considerable intensity between 11.30 and 12.00 today and then again starting from 13.00 in the following hours. The Space meteorological forecast center of the US agency Noaa confirms that aExpulsion of Coronal Massa or Cmethat is, an expulsion of matter by the Sun in the form of plasmais continuing to hit the Earth’s magnetic field But at the moment it is still impossible to understand whether the intensification of the storm is due to the arrival of one second cme or if it is still the passage of the Beforearrived around 19.30 Italian yesterday.
The storm is therefore approaching the intensity of that verified to May 2024which caused electrical networks problems and made it The signs for hours unusable for the satellite navigation: “The conditions are there, but there is no certainty – comments Messreotti – all that remains is to follow the evolution of the phenomenon”. The storms of G4 class can cause voltage problems widespread, Blackout radio, GPS interruptions and can Change the trajectory of the satellites in Low terrestrial orbit. At the moment, however, it is not yet known if the storm caused some damage: «It is too early – says Messerotti – to have detailed findings».
