Map: Who may see northern lights as coronal mass ejection hits Earth

UNITED STATES, AUG 11 – A geomagnetic storm from a recent solar flare may produce auroras visible in up to 18 northern U.S. states, with NOAA forecasting a moderate G2 storm peak around 2 a.m.

  • On Friday, the National Oceanic and Atmospheric Administration forecast auroras over nearly all of Canada, excluding only the easternmost Nova Scotia and Newfoundland.
  • Amid peak solar activity, a coronal mass ejection lifted off the Sun on Aug. 5 and a coronal hole high speed stream will drive geomagnetic storming later this week.
  • The Space Weather Prediction Center issued a G1-G2 storm watch for Aug. 8-9, with a small chance of G3 on Aug. 7-8.
  • Skywatchers in the U.S. from Alaska to Illinois may see northern lights tonight, as 18 states are forecasted to have opportunities for viewing.
  • While mainly manageable, the geomagnetic storms may cause minor disruptions to power grids, pipelines, and GPS during the upcoming aurora visibility period.
