Overview

• NOAA’s Space Weather Prediction Center forecasts G2 conditions late Oct. 16 with Kp near 5–6, followed by G1 activity into Oct. 17.
• Auroras may be visible across northern U.S. states from New York to Idaho, across much of Canada, and as far south as northern UK regions such as Yorkshire, weather permitting.
• The storm is driven by several CMEs launched Oct. 11–13 that could arrive in quick succession, a setup analysts say may amplify geomagnetic effects.
• Expected impacts are limited to minor power‑grid fluctuations, intermittent radio or GPS degradation, and increased satellite drag rather than widespread outages.
• Public guidance highlights NOAA’s 30‑minute aurora forecast and mobile apps for real‑time alerts, plus viewing from dark locations after sunset into the early hours of Oct. 17.
