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.
On March 10, 1989, a huge solar flare caused a storm that surged the Quebec power grid, which was out of commission for eight long hours on a weekday morning, affecting about 6 million people.
A geomagnetic storm is heading to Earth, with the possibility to disrupt GPS and communications. It could also bring the northern lights to Northern California, much farther south than is typical.

On 8 May 2024, a solar active region which had been assigned the NOAA region number 13664 (AR3664) produced an X1.0-class and multiple M-class solar flares and launched several coronal mass ejections (CMEs) toward Earth. [6] On 9 May, the active region produced an X2.25- and X1.12-class flare each associated with a full-halo CME.
May 2024 solar storms: X1.2(X1.3)-class flares [93] and X4.5-class flare. [94] The flares with a magnitude of 6–7 occurred between 30 April and 4 May 2024. On 5 May the strength of the solar storm reached 5 points, which is considered strong according to the K-index. The rapidly growing sunspot AR3663 became the most active spot of the 25th ...
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. Will northern lights, solar storms cause ...
