When was the last time a solar storm hit Earth?

Direct measurements and/or visual observations

Was there a massive solar flare in 2012?

A huge coronal mass ejection — a large cloud of hot plasma sent into space — erupted from the sun on July 23, 2012. The CME went through Earth’s orbit, and had it happened only one week earlier, our planet would have been in the way and faced severe technological consequences.

What was DST for the July 2012 CME?

estimated Dst for the July 2012 storm. “If that CME had hit Earth, the resulting geomagnetic storm would have registered a Dst of -1200, comparable to the Carrington Event and twice as bad as the March 1989 Quebec blackout.”

Has there been any comparable solar storm after the Carrington Event that almost hit the Earth?

The solar storm of 2012, as photographed by STEREO, was a CME of comparable strength to the one which is thought to have struck the Earth during the 1859 Carrington Event.

What caused the Carrington Event?

The Carrington Event was caused by a massive solar storm, and one that would cause widespread disruption today, considering that fact that our reliance on electronic devices has grown even further.

What happened July 23rd 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.

Could solar flare destroy Earth?

It was, quite literally, off the charts. Solar flares are mostly harmless and don’t pose much of a threat to humans on the surface of the Earth. What could cause some problems, however, are coronal mass ejections (CMEs) which are sometimes conflated with solar flares in popular parlance.

How strong was the solar flare that caused 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.

Could a Carrington-class solar storm happen in the next 10 years?

Riley calculated that in the next 10 years, there is a 12 percent chance that a Carrington-class solar storm could happen. He used a parameter called Dst, “disturbance – storm time,” that looks at how much the magnetic field around Earth shakes when coronal mass ejections hit.

What was the solar storm of 2012?

Baker, along with colleagues from NASA and other universities, published a seminal study of the storm in the December 2013 issue of the journal Space Weather. Their paper, entitled “A major solar eruptive event in July 2012,” describes how a powerful coronal mass ejection (CME) tore through Earth orbit on July 23, 2012.

Did a solar eruptive event happen in July 2012?

Their paper, entitled “A major solar eruptive event in July 2012,” describes how a powerful coronal mass ejection (CME) tore through Earth orbit on July 23, 2012. Fortunately Earth wasn’t there. Instead, the storm cloud hit the STEREO-A spacecraft.

Was there a near-miss solar superstorm in 2012?

A ScienceCast video recounts the near-miss of a solar superstorm in July 2012. Play it Baker, along with colleagues from NASA and other universities, published a seminal study of the storm in the December 2013 issue of the journal Space Weather.
