Overview
- Russia’s Laboratory of Solar Astronomy at IKI RAN reported the arrival of the third coronal mass ejection, confirming the sequence has reached Earth.
- The lab said auroras rank among the strongest in a decade, with potential visibility from roughly 45 degrees latitude as the oval extends over Europe and Canada.
- Monitoring on the lab’s site shows an ongoing geomagnetic storm around G3.3, which corresponds to a strong event.
- Earlier, satellites at the Sun–Earth L1 point detected the first CME, and models indicated three impacts increasing in intensity with the final, fastest ejecta posing the greatest risk.
- Scientists noted high uncertainty in short‑term forecasts and said earlier model timing diverged from observations, including expectations that the fastest cloud could overtake slower ones.
