Did a solar flare almost hit Earth 2012?
The solar storm of 2012 was an unusually large and strong coronal mass ejection (CME) event that occurred on July 23 that year. It missed Earth with a margin of approximately nine days, as the equator of the Sun rotates around its own axis with a period of about 25 days.
When was the last major solar flare that hit Earth?
Carrington Event

Can solar flares destroy the Earth?
Not really. While electromagnetic fluctuations from solar flares can disrupt satellites, interrupt power grids, or jam communication equipment, “there simply isn’t enough energy in the sun to send a killer fireball 93 million miles to destroy Earth,” says NASA.
What year was the largest solar flare on record recorded?
2001
At 4:51 p.m. EDT, on Monday, April 2, 2001, the sun unleashed the biggest solar flare ever recorded, as observed by the Solar and Heliospheric Observatory (SOHO) satellite.
What would happen if a solar flare hit Earth?
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.
Was there a solar maximum in 2012?
On July 12, 2012, the sunspot’s magnetic field erupted, producing an X-class solar flare and hurling a billion tons of electrified plasma toward our planet. NASA’s twin STEREO probes and the European Space Agency’s Solar and Heliospheric Observatory monitored the CME as it billowed away from the sun.
Will a solar flare hit Earth in 2025?
The sun’s activity fluctuates on an 11-year cycle, which had been at its minimum level of activity in the past years. Scientists predict that the solar cycle will hit its maximum in 2025; sunspots, CMEs and solar storms are likely to continue increasing in frequency throughout the coming years.
What happens every 11 years on the sun?
About every 11 years, the Sun’s magnetic field does a flip. In other words, the north pole becomes the south pole, and vice versa. This flip is one aspect of the roughly 11-year activity cycle the Sun experiences as its magnetic field evolves slowly over time.
Can solar flares harm humans?
Although eruptions of energy from the sun can damage satellites, power infrastructure and radio communications, they do not harm people.
What happens if a CME hits Earth?
If a CME collides with the Earth, it causes a geomagnetic storm, and the US-based Space Weather Prediction Center under the National Oceanic and Atmospheric Administration (NOAA) has released a warning about a possible G2 (Moderate) geomagnetic storm.
