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]
The Halloween solar storms were a series of solar storms involving solar flares and coronal mass ejections that occurred from mid-October to early November 2003, peaking around October 28–29. [ 1][ 2][ 3] This series of storms generated the largest solar flare ever recorded by the GOES system, modeled as strong as X45 (initially estimated at ...
The solar storms of May 2024 were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25. The geomagnetic storm was the most powerful to affect Earth since March 1989 , [ a ] and produced aurorae at far more equatorial latitudes than usual in both ...

Four solar flares occurred within 5 days from sunspot AR 12192, which is both the largest sunspot of solar cycle 24 and the largest since 1990. On October 19 there was a major X1.1-class solar flare. On October 22 an M8.7-class flare was followed by an X1.6 event. The October 24 X3.1-class solar flare was strong enough to trigger a radio blackout.
The first visible and electromagnetic effects of a solar flare reach observers on Earth at the speed of light, which means they were spotted about eight minutes after they occurred on the surface ...
In 2012, a solar flare far larger than either the May storm or the one now in progress — described by NASA as “big enough to knock modern civilization back to the 18th century” — barely ...
Deaths. Almost 100. The Northeast blackout of 2003 was a widespread power outage throughout parts of the Northeastern and Midwestern United States, and most parts of the Canadian province of Ontario on Thursday, August 14, 2003, beginning just after 4:10 p.m. EDT. [ 1 ] Most places restored power by midnight (within 7 hours), some as early as 6 ...
