AI Overview
Key Facts and Timeline
- The Solar Flare: On September 1, 1859, British astronomers Richard Carrington and Richard Hodgson independently observed a brilliant flash of white light on the sun near a massive sunspot group. This was the first time anyone directly recorded a solar flare.
- The Coronal Mass Ejection (CME): The sun unleashed a massive cloud of magnetized plasma that raced toward Earth at extreme speed, completing the journey in about 17.5 to 18 hours instead of the usual multi-day transit.
- Geomagnetic Storm Peak: The storm peaked on September 2, 1859, sending Earth's magnetometers completely off-scale.
Impacts
- Global Auroras: Vivid northern and southern lights lit up the night sky across the planet, appearing as far south as Cuba, Hawaii, Central America, and the Caribbean. The auroras were so bright that people in the Rocky Mountains woke up and began making breakfast at 1:00 AM, thinking the sun had risen.
- Telegraph Failures: The surge of electrical current overwhelmed global telegraph networks. Operators received electrical shocks, and some telegraph systems continued to function even after their batteries were completely disconnected. Sparks flew from the equipment, and paper in some telegraph offices caught fire.
