    en.wikipedia.org/wiki/March_1989_geomagnetic_storm

    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] Several days later, at 01:27 UT on March 13, a severe geomagnetic storm struck Earth.

    [citation needed] This can result in events such as the March 1989 geomagnetic storm. CMEs, along with solar flares, can disrupt radio transmissions and cause damage to satellites and electrical transmission line facilities, resulting in potentially massive and long-lasting power outages.

    en.wikipedia.org/wiki/Geomagnetic_storm

    A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave. The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a corotating interaction region (CIR), a high-speed stream of solar wind originating ...

    The geomagnetic storm causing this event was itself the result of a Coronal Mass Ejection on March 9, 1989. [7] A few days before, on March 6, 1989, a very large X15 solar flare also occurred. [8] At 2:44 am on March 13, 1989, a severe geomagnetic storm struck Earth. [9] [10] The storm began on Earth with extremely intense auroras at the poles.

    On 13 March 1989, a severe geomagnetic storm caused the collapse of the Hydro-Québec power grid in a matter of seconds as equipment protective relays tripped in a cascading sequence of events. [5] Six million people were left without power for nine hours, with significant economic loss.
