Severe geomagnetic storm driven by a slow ICME: Revisiting the August 2018 event

Key Points

• The severe geomagnetic storm was linked to a slow interplanetary coronal mass ejection (ICME).
• The storm effects were most pronounced, impacting satellite operations and communication systems significantly.
• Observational analysis examined geomagnetic data from August 2018, focusing on solar activity and magnetic field variations.
• These findings highlight the necessity for improved forecasting of space weather events to mitigate risks.
