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.
In early August 1972, a series of flares and solar storms peaks with a flare estimated around X20 producing the fastest CME transit ever recorded and a severe geomagnetic and proton storm that disrupted terrestrial electrical and communications networks, as well as satellites (at least one made permanently inoperative), and spontaneously ...
The Sun has unleashed a powerful solar flare, Nasa has said. The flare, designated X2.3, belongs to the most intense X class of flares. It was spotted by Nasa’s Solar Dynamics Observatory, which ...
The geomagnetic storm causing this event is believed to be the result of two separate events known as coronal mass ejections (CME) on March 10 and 12, 1989. [2] A few days before, on March 6, a very large X15-class solar flare also occurred. [3]
Programming note: Tune in to CNN NewsNight: Solar Storm, hosted by Abby Phillip and Bill Weir, tonight from 10 p.m. to 12 a.m. ET. For the latest on the massive solar storm, head over to CNN’s ...
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 ...
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 ...
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 ...
