However, when this layer is ionized, it absorbs frequencies below 30 MHz, leading to shortwave radio blackouts. The Sun emitted a strong solar flare on Nov. 6, 2024, peaking at 8:40 a.m. ET.

Fabricated radio-wave absorber and measurement setup (a) at 30 GHz and (b) at 150 GHz. Measurement results at 30 GHz and (d) at 150 GHz. 5G wireless communication services have rapidly expanded ...

a shortwave radio blackout followed in its wake that disrupted high frequency radio signals for different parts of the Atlantic Ocean in the southern hemisphere including in South America and Africa.
