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.
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.
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 is defined [5] by changes in the Dst [6] (disturbance – storm time) index. The Dst index estimates the globally averaged change of the horizontal component of the Earth's magnetic field at the magnetic equator based on measurements from a few magnetometer stations.
