Top 50 Geomagnetic Storms of 2022
An Overview
On this page, you will find a comprehensive review of the strongest geomagnetic storms that transpired throughout 2022, along with quick links to additional information. Geomagnetic storms often arise due to disruptions on the Sun, primarily caused by coronal mass ejections (CMEs).
Classification of Geomagnetic Storms
Geomagnetic storms are categorized into three distinct intensity levels based on their Dst (disturbance storm time) index:
- Moderate: Dst minimum of -50 nT
- Intense: Dst minimum between -100 nT and -250 nT
- Extreme: Dst minimum of -250 nT or below
Impact of Geomagnetic Storms
Geomagnetic storms can have a significant impact on Earth, causing various disruptions, including:
- Power outages
- Interruptions in communication systems
- Damage to satellites and other electronic devices
- Aurora displays at lower latitudes
In conclusion, understanding the occurrence and intensity of geomagnetic storms is crucial for mitigating their potential risks. By monitoring these events, we can better prepare and respond to their impact, ensuring the resilience of our infrastructure and protecting our technological advancements.
