Biggest solar flare since 2017 erupts from sun and Earth is in the firing line
On Oct. 3, the sun released the most powerful solar flare this solar cycle, a colossal X9.05 eruption.
The X9.05 solar flare peaked at 8:10 a.m. EDT(1210 GMT), triggering shortwave radio blackouts over Africa and Europe, the sunlit portion of Earth at the time of eruption.
