Comparable in size to the May 2024 storms. [46] Oct 1903 Solar storm of Oct-Nov 1903 An extreme storm, estimated at Dst −531 nT arose from a fast CME (mean ≈1500 km/s), occurred during the ascending phase of the minimum of the relatively weak solar cycle 14, which is the most significant storm on record in a solar minimum period. Aurora was ...
Solar storms can also push satellites out of orbit. In very severe cases, solar storms can affect power grids. In 1989, a geomagnetic storm wiped out Quebec's electricity and caused other power ...
A "severe" solar storm could make the northern lights visible in the U.S. farther south than usual while also posing the potential to disrupt modern technology, according to the National Oceanic ...
A powerful solar flare, solar superstorm or a solar micronova, which is a drastic and unusual decrease or increase in the Sun's power output, could have severe consequences for life on Earth.

Coronal mass ejections are also important drivers of space weather, as they can compress the magnetosphere and trigger geomagnetic storms. Solar energetic particles (SEP) accelerated by coronal mass ejections or solar flares can trigger solar particle events, a critical driver of human impact space weather, as they can damage electronics ...
Geomagnetic storms can have an impact on infrastructure in near-Earth orbit and on Earth’s surface, potentially disrupting communications, the electric power grid, navigation, radio and ...
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 ...
The most intense solar storm in recorded history, in 1859, prompted auroras in central America and possibly even Hawaii. “We are not anticipating that” but it could come close, NOAA space ...
