A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
The incoming solar storm arose from a strong flare near “Region 3500” on the Sun, scientists say. Solar storms are known to interfere with the Earth’s magnetic field and cause damages to ...
NASA’s Solar Dynamics Observatory captured this image of a solar flare on Oct. 1, 2024. NASA had a busy start to October, as the agency announced that the sun emitted several major solar flares ...
Given that solar wind is moving faster than the speed of sound, it will reach Earth only 20 to 45 minutes after passing that 1-million-mile marker in space. Read more: NASA says the truth is out ...
A severe geomagnetic storm reached Earth on ... they typically appear — on Thursday evening due to a powerful solar flare and coronal mass ejection ... storm to hit Earth was in 2003, resulting ...
The March 1989 geomagnetic storm knocked out power across large sections of Quebec, while the 2003 Halloween solar storms registered the most powerful solar explosions ever recorded. On 23 July 2012, a "Carrington-class" solar superstorm (solar flare, CME, solar electromagnetic pulse) was observed, but its trajectory narrowly missed Earth.
The solar storms of May 2024 were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25. The geomagnetic storm was the most powerful to affect Earth since March 1989 , [ a ] and produced aurorae at far more equatorial latitudes than usual in both ...
A "severe" solar storm could make the northern lights visible in the U.S. farther south than usual while also posing the potential to disrupt modern technology, according to the National Oceanic ...
