Overview
- An X‑class flare from active region AR4274 and multiple coronal mass ejections triggered G4 (severe) geomagnetic conditions confirmed by NOAA’s Space Weather Prediction Center.
- Auroras were observed far south of the polar regions, with verified sightings across the southern United States, Mexico, parts of South America, Europe, Australia and New Zealand.
- Agencies reported technological effects including GPS inaccuracies, high‑frequency radio disruptions and satellite anomalies, with grid operators warned about potential voltage control issues.
- Forecasters noted several CME arrivals and cautioned that another, possibly stronger, CME could still reach Earth, extending disturbances over the next 24–72 hours.
- Authorities including NASA, ESA and UNAM’s SCIESMEX emphasized no direct health risk to people, as operators and the public were urged to follow official advisories; Blue Origin postponed a launch due to space‑weather risks.
