A geomagnetic storm is forecasted to occur on September 12-13, potentially causing interruptions in radio signal transmissions, the Astrophysics Department at the Physics Faculty of Baku State University told Report.

The increased solar activity, attributed to continuous M-class flares, has elevated the Sun’s activity to a high level. These flares are known to block and hinder the propagation of radio waves.

A coronal mass ejection (CME) from the northwest part of the Sun on September 10 is expected to trigger the geomagnetic storm on Earth, starting from the afternoon of September 12 and lasting until approximately 18:00 (GMT+4) on September 13. During this period, disruptions in the transmission and reception of radio signals may occur.

Currently, the geomagnetic field is quiet but unstable. The effects of the CME will become apparent on Earth between September 12 and 13.

The geomagnetic storm is predicted to reach G1 (mild) levels on the night of September 12, escalate to G2 (moderate) levels until 08:00 (GMT+4) on September 13, and then return to G1 levels until 20:00. Following this, the geomagnetic field is expected to stabilize and return to a quiet state.
