Geomagnetic storms from the June 1 coronal mass ejection are set to persist into June 3, offering prime aurora viewing between 10 p.m. to 2 a.m. under dark skies.

Overview

  • A June 1 solar eruption unleashed charged particles that sparked G3-level geomagnetic storms around Earth’s poles.
  • The aurora borealis has been visible from Alaska through Michigan, with bright displays reported across central Canada and northern UK.
  • NOAA and the Met Office report that geomagnetic activity will weaken but continue to produce intermittent auroras into the night of June 3.
  • Solar Cycle 25 is at its peak, driving more frequent and intense solar wind events that sustain heightened aurora activity into 2026.
  • Stargazers are advised to head to dark, elevated spots away from light pollution between late evening and early morning for the best chance to see the lights.
