Massive CME to strike within 24 hours — auroras possible across 24 US states

A massive coronal mass ejection is forecast to impact Earth within 24 hours, with auroras expected across as many as 24 U.S. states from Alaska to Colorado tonight. Space‑weather forecasters are tracking the incoming CME as it approaches the magnetosphere.

Briefing

What Hype is tracking

The incoming CME is expected to arrive within 24 hours and could produce auroral displays visible across 24 U.S. states; operators should note the timing and regional extent of the event.
Elevated geomagnetic activity from CMEs has previously led to severe (G4–G5) space‑weather impacts on satellites, GNSS and power systems — see past G4–G5 events (source:af6ac66e-d45c-4a7f-b072-f6d14d7503f4).
New research identifying early radio precursors to auroral substorms may provide actionable warning time for operators monitoring this CME (source:34ba3030-7261-44e5-a17a-b7d0e26b4183).
