The brief
A major X1.1 solar flare erupted at 20:50 UTC on June 30, 2026, causing radio blackouts across North America. The flare also released a coronal mass ejection (CME) headed towards Earth. Coverage from Yahoo, Space, and India Today emphasizes the potential for geomagnetic storms and auroras.
The Watchers and NASA Science also reported on the event. The flare prompted a solar radiation storm warning, which was later canceled. Coverage does not yet specify the extent of the radio blackouts or the expected duration of the geomagnetic storm.
Watch for updates on the geomagnetic storm's impact on Earth, particularly around the July 4 weekend. Coverage from outlets like Space and The Watchers may provide more details on potential aurora sightings.
