Geomagnetic Storm Sparks Widespread Aurora Displays Across Northern Hemisphere

A rare double solar eruption has triggered a G3 geomagnetic storm, offering aurora sightings in 18 U.S. states, parts of Canada, and Europe through Wednesday night.

Overview

  • Two coronal mass ejections (CMEs) from a double solar eruption are driving the ongoing G3 geomagnetic storm, with auroras visible farther south than usual.
  • Auroral activity is forecast to peak on Wednesday night, with viewing opportunities in northern U.S. states, Canada, and northern parts of the UK, weather permitting.
  • The NOAA Space Weather Prediction Center advises optimal viewing between 10 p.m. and 2 a.m. in dark, clear areas away from light pollution.
  • The heightened solar activity occurs during the solar maximum of Solar Cycle 25, marked by frequent sunspot activity and rare solar eruptions.
  • The storm may cause minor disruptions to satellites and communication systems, though no significant technological impacts are expected.
