Overview

  • The NOAA Space Weather Prediction Center has issued a G2-level geomagnetic storm watch for June 14, forecasting a Kp index up to 5.67 and moderate storming.
  • Auroras may stretch from Washington and Idaho through New York and Maine, expanding visibility southward into parts of the Midwest.
  • Optimal viewing is expected between 10 p.m. and 2 a.m. local time from dark, north-facing sites away from city lights.
  • NASA and NOAA project that solar maximum conditions will sustain strong aurora displays through early 2026 after a 500-year peak in 2024.
  • In the UK, AuroraWatch UK issued red alerts for Friday night and photographers have already captured displays over Breydon Water and Oxfordshire.
