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.
Solar storm of Oct-Nov 1903 An extreme storm, estimated at Dst −531 nT arose from a fast CME (mean ≈1500 km/s), occurred during the ascending phase of the minimum of the relatively weak solar cycle 14, which is the most significant storm on record in a solar minimum period. Aurora was conservatively observed to ≈44.1° ILAT, and ...
The event took place more than 14,000 years ago, scientists said.
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 ...

The largest recorded geomagnetic perturbation, resulting presumably from a CME, was the solar storm of 1859. Also known as the Carrington Event , it disabled parts of the newly created United States telegraph network, starting fires and electrically shocking some telegraph operators.
The intense solar wind and particle storm associated with the CMEs led to one of the largest decreases in cosmic ray radiation from outside the Solar System, known as a Forbush decrease, ever observed. [23] Solar energetic particle (SEP) onslaught was so strong that the Forbush decrease in fact partially abated. [24]
