After the third consecutive day, the intensity of the geomagnetic storm that began on January 19 remains strong. According to the latest data from the National Aeronautics and Space Administration (NOAA)'s Space Weather Prediction Center, it has reached a G3 level . Yesterday, however, it had once again reached a G4 level.

G3 storms can cause problems with power transmission lines and satellite communications, and brief disruptions to GPS navigation systems and radio communications.

The storm allowed much of Europe, including Italy, to witness the spectacle of the Northern Lights at lower latitudes . In the early hours of yesterday, the phenomenon seemed to be already waning, but instead it intensified again.

The phenomenon was triggered by the arrival of a rapid coronal mass ejection . The geomagnetic storm was preceded and accompanied by a solar radiation storm .

This type of phenomenon can pose a problem for anything that is outside the protection offered by the Earth's atmosphere and magnetic field, including astronauts, spacecraft, satellites, and aircraft that reach very high altitudes.
