BSU’s Department of Astrophysics: "Strong Geomagnetic Storm Expected on October 10-12"
The Department of Astrophysics at Baku State University (BSU) has announced that a strong geomagnetic storm is expected to occur between October 10-12, following the observation of powerful X-class solar flares. These flares, known to significantly disrupt radio wave propagation, include a particularly strong X1.8-class flare that erupted on the night of October 9. As a result, intense radiation and a coronal mass ejection (CME) are predicted to impact Earth during this period.
According to BSU's Department of Astrophysics, solar activity will remain at a heightened level until October 11-12, with further X-class flares likely. Solar storms of S1-S2 intensity (small to moderate) will persist until October 10, after which activity is expected to subside to background levels. The solar wind, excited by the CME from the X1.8 flare, is traveling at speeds of 1200-1400 km/s, and will reach Earth at speeds of 600-700 km/s. Multiple CMEs are causing the solar wind to be in a shock state.
The impact of the CME will be felt on Earth from October 10 to 12, with the intensity decreasing after October 12. Initially, the effects will be detected by satellites within 30-45 minutes, followed by observations through ground-based magnetometers. During this time, Earth's geomagnetic field will be in an excited state, with a geomagnetic activity index of 6-7. A G4 (strong) geomagnetic storm is predicted for October 10-11, and variations in the geomagnetic field may occur due to fluctuations in Earth’s magnetic field.
