Overview
- NOAA’s Space Weather Prediction Center confirmed severe G4 conditions on Wednesday as the most energetic coronal mass ejection in a recent series arrived.
- Auroras were seen far from the poles, with reports from Texas, Alabama and Florida, plus widespread sightings across Mexico and parts of South America.
- NOAA’s Shawn Dahl reported some impacts to GPS communications and power‑grid voltage control, with additional risk to HF radio and satellite links.
- The activity stems from solar active region AR4274, which produced powerful X‑class flares, including an X5.1 eruption with Earth‑directed material.
- Agencies say further CMEs are likely in the next 48–72 hours and urge operators to keep mitigation measures in place, noting no direct health risk to the public.
