A geomagnetic storm is forecast to occur on Earth between October 4 and 5 due to increased solar activity, according to the Department of Astrophysics at Baku State University (BSU).

Solar activity is expected to remain at a medium-high level, with a likelihood of class M solar flares, which weakly disrupt radio wave propagation, and isolated class X flares, which are more intense. The storm will be driven by high-speed solar wind flows emerging from coronal holes, causing elevated levels of geomagnetic and solar wind activity.

A G2 (moderate) geomagnetic storm is predicted to begin on the night of October 4, lasting until around 8:00 a.m. the next day. Afterward, the geomagnetic field is expected to return to normal levels. However, another G2-level storm is anticipated to start at 9:00 p.m. on October 4, followed by a G1 (minor) storm between 1:00 a.m. and 9:00 a.m. on October 5.

These geomagnetic disturbances may have effects on satellite operations, radio communications, and power systems, although their impact is expected to be moderate.
