What is the Carrington Event and why is it important?
The Carrington Event was the most intense geomagnetic storm in recorded history, peaking from 1 to 2 September 1859 during solar cycle 10. It created strong auroral displays that were reported globally and caused sparking and even fires in multiple telegraph stations.
What happened during the Carrington Event?
The 1859 Carrington Event caused the Northern Lights to light up night skies around the globe. Typically only seen near polar regions, the bright auroras were viewed all the way from the northern hemisphere to southern areas such as Cuba, Hawaii, and Columbia.
Why is it called the Carrington Event?
The Carrington Event is named after British astronomer Richard Carrington, who was particularly interested in observing the sun, and dark areas on its surface known as sunspots. On September 1, 1859, Carrington was peering at the sun through a telescope fitted with protective dark filters.
What class of flare was the Carrington Event?
By comparison of the magnetogram with that of other more recent X-class flares, the soft X-ray intensity of the Carrington flare was estimated to be X45. This was significantly larger than the X35 class event of the famous Halloween storm of 2003, which was the 6th largest geomagnetic storm in history.
What strength was the Carrington Event?
Studies of the very limited magnetic data from the Carrington Event peg its intensity at anywhere from –850 to –1,050 nT. According to Love’s study, the 1921 storm, however, came in at about –907 nT. “The 1921 storm could have been more intense than the 1859 storm,” Love says.
What would happen if Earth got hit by a solar flare?
If a “Carrington-sized” solar flare were to hit Earth today, it would emit X-rays and ultraviolet light, which would reach Earth’s atmosphere and interfere with electronics, as well as radio and satellite signals.
What would happen to an astronaut in a solar storm?
What is the danger of a solar storm in space? Very high-energy particles, such as those carried by CMEs, can cause radiation poisoning to humans and other mammals. They would be dangerous to unshielded astronauts, say, astronauts traveling to the moon. Large doses could be fatal.
Can a solar storm destroy the Internet?
The internet, telephones, and other electronic devices can all be disrupted by a large geomagnetic storm. The internet, transit and telecommunications systems, base station, and power grids might all be affected by a solar storm, bringing civilization to a standstill.
