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.
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.
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 ...

Mar 1989 March 1989 geomagnetic storm: Most extreme storm of the Space Age by several measures. Outed power grid of province of Quebec. [68] Caused interference to United States power grid. [69] Aug 1989 [70] Nov 1991 Geomagnetic storm of November 1991 An intense solar storm with about half the energy output of the March 1989 storm.
[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. [38] [39]
The flares and CMEs of the August 1972 solar storms were similar to the Carrington event in size and magnitude; however, unlike the 1859 storms, they did not cause an extreme geomagnetic storm. The March 1989 geomagnetic storm knocked out power across large sections of Quebec, while the 2003 Halloween solar storms registered the most powerful ...
