One of the most powerful solar flares on record happened in 2003, according to NASA, which overloaded the sensors measuring it. Scientists later estimated that flare to be about X45. Scientists ...
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 ...
In addition to possibly bringing the northern lights to Ohio, a severe geomagnetic storm might knock out cellphones and the power grid. What to know.
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.
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 Halloween solar storms were a series of solar storms involving solar flares and coronal mass ejections that occurred from mid-October to early November 2003, peaking around October 28–29. [ 1 ] [ 2 ] [ 3 ] This series of storms generated the largest solar flare ever recorded by the GOES system, modeled as strong as X45 (initially ...
