Overview

  • Skywatchers reported vivid displays from Sept. 1–3, with sightings as far south as New York during the Labor Day period.
  • Geomagnetic activity registered at G2 before strengthening to G3 as the main disturbance reached Earth.
  • The eruption traced to sunspot AR 4199, where a long-duration M2.7 flare on Aug. 30 launched a fast coronal mass ejection.
  • The Space Weather Prediction Center forecast expanded auroral visibility, and NOAA confirmed observations at lower-than-usual latitudes.
  • Photos and reports flooded social media from the northern United States and across Europe, including Scotland, Ireland, France, the Netherlands and Latvia, as well as Canada.
