March 1989 geomagnetic storm
The March 1989 geomagnetic storm occurred as part of severe to extreme solar storms during early to middle 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. Other historically significant solar storms occurred later in 1989, during a very active period of solar cycle 22.
