Strongest solar flare of 2025 erupts from sun, sparking radio blackouts across Europe, Asia and the Middle East
X2.7-class eruption from sunspot AR4087 disrupts radio signals as the active region rotates toward Earth, raising the risk of more flares ahead.
The eruption peaked at 4:25 a.m. EDT (0825 GMT), triggering strong R3-level radio blackouts across Europe, Asia and the Middle East — the sunlit side of Earth at the time — as sunspot region 2087 crackles with activity.
