Answered

What caused the radio blackouts in North America?

The radio blackouts were caused by a major X1.1 solar flare that erupted at 20:50 UTC on June 30, 2026.

What is a coronal mass ejection (CME)?

A coronal mass ejection is a significant release of plasma and magnetic field from the solar corona. The CME released by the recent solar flare is headed towards Earth and could spark geomagnetic storms and auroras.

When is the geomagnetic storm expected to hit Earth?

The geomagnetic storm is expected to hit Earth on July 2, 2026, according to coverage from AKIpress News Agency.
