What is Carrington Age?
Carrington Age refers to the time elapsed since the last observed Carrington Event, a powerful geomagnetic storm that occurred in 1859. Named after British astronomer Richard Carrington, who witnessed the associated solar flare, this event caused widespread disruptions to telegraph systems worldwide.
The Carrington Event highlighted the potential risks posed by extreme space weather to modern infrastructure and technologies. Since then, Carrington Age has become a key metric used to assess the likelihood of a similar event occurring again.
Scientists estimate that the average Carrington Age is approximately 100 years, although the actual interval between events can vary significantly. The longest recorded Carrington Age was 153 years, while the shortest was just 5 years.
Understanding Carrington Age is crucial for developing effective mitigation strategies and safeguarding critical infrastructure from the potentially catastrophic effects of geomagnetic storms.

Variability
The variability of Carrington Age, ranging from 5 to 153 years, is a significant aspect to consider when assessing the risk and impacts of Carrington Events.
- Natural Variability: The variability in Carrington Age is primarily attributed to the unpredictable nature of solar activity. The Sun's magnetic field undergoes complex changes, leading to variations in the frequency and intensity of geomagnetic storms.
- Historical Evidence: Records of past Carrington Events demonstrate the variability in their occurrence. The shortest Carrington Age on record is 5 years, between the events of 1859 and 1864, while the longest is 153 years, between 1610 and 1763.
- Implications for Risk Assessment: The variability of Carrington Age poses challenges in accurately predicting the timing of future events. A shorter Carrington Age indicates an increased likelihood of an event occurring within a shorter timeframe, while a longer Carrington Age suggests a lower risk.
- Mitigation Strategies: Understanding the variability of Carrington Age is crucial for developing effective mitigation strategies. By considering the potential range of recurrence intervals, policymakers and infrastructure operators can implement measures to minimize the impacts of future events, regardless of their timing.
In summary, the variability of Carrington Age highlights the inherent unpredictability of extreme space weather events. It underscores the need for continuous monitoring, research, and robust mitigation strategies to safeguard critical infrastructure and enhance societal resilience against the potential impacts of Carrington Events.
