22 States To See Aurora Tuesday As Rare ‘Cannibal CME’ Strikes Earth
NOAA warns of severe geomagnetic storms with a G4 alert that may disrupt communications and power grids while creating auroras visible as far south as Alabama.
- On November 12th, the National Oceanic and Atmospheric Administration issued a Severe Geomagnetic Storm Watch as auroras could appear across much of the northern United States and reach Alabama and Northern California.
- A series of CMEs since Sunday has erupted, with the latest linked to an X5.1-class solar flare from Region 4274 around 4 a.m., complicating timing forecasts.
- Historical events show that geomagnetic storms can disrupt power grids, communication networks, GPS systems and satellites, but utilities and companies can activate safeguards; the 1859 Carrington Event and 1989 Quebec blackout demonstrate real impacts.
- NOAA urged U.S. stargazers to monitor the sky after dark Tuesday and check spaceweather.gov, as forecasters say clouds are clearing and the best viewing window is 10 p.m. to 2 a.m.
- Unusually active solar conditions have pushed auroras far from high latitudes to Germany, the United Kingdom, New England and New York City, while NOAA forecasters await solar wind measurements about 1 million miles from Earth.

Geomagnetic storm could make aurora visible for much of U.S.
A severe geomagnetic storm is forecast to hit Earth’s magnetic field on Wednesday, which could cause widespread disruption to infrastructure technology and make northern lights visible for much of the northern half of the U.S.The National Oceanic and Atmospheric Administration on Tuesday issued a G4, or severe, geomagnetic storm watch in response to recent coronal mass ejections, or CMEs, from the sun. The highest geomagnetic storm level is G5, …
