The strongest magnetic storm in recent years is being observed on Earth

A strong magnetic storm of G3.33 class is being observed on Earth, reported by Zemlya.uz.

According to specialists, this event is the second strongest geomagnetic disturbance recorded since the beginning of 2026 and is directly linked to a sharp increase in solar activity. The natural phenomenon is significantly affecting Earth’s magnetic field.

According to data from the Solar Astronomy Laboratory of the Institute of Space Research of the Russian Academy of Sciences, the magnetic storm began about a day later than initially forecast. Scientists note that Earth’s magnetic field has remained under the influence of plasma streams ejected from the Sun over the past twenty-four hours.

The initial peak of these streams reached Earth around 16:00 local time on July 3. The most significant changes in the situation were observed during the night of July 3–4.

It was precisely during this period that the speed of the solar wind sharply increased and the direction of the interplanetary magnetic field changed. As a result, a strong geomagnetic storm of G3.33 class developed and maintained high activity for several hours.

Experts remind that solar flares are classified into five main classes based on the intensity of their X-ray radiation. Such powerful geomagnetic storms can, in some cases, cause technical disruptions in power grids and communication systems.

Additionally, this event may negatively affect the migration patterns of birds and certain animals. Furthermore, during periods of heightened geomagnetic activity, auroras may be observed over a wider area than usual.

Currently, scientists are continuously monitoring solar activity and have the situation under full control. The public, especially individuals with health conditions, is advised to exercise caution on such days.
