The March 1989 geomagnetic storm occurred as part of severe to extreme solar storms during early to mid March 1989, the most notable being a geomagnetic storm that struck Earth on March 13. This geomagnetic storm caused a nine-hour outage of Hydro-Québec's electricity transmission system. The onset time was exceptionally rapid. [1] Other ...
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.
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.

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 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 ...
