Mariners and ham radio operators have noticed a brief communications blackout at frequencies below about 10 MHz.

It is still unknown if the flare also produced a coronal mass ejection. If so, it would miss Earth because the sunspot is not centered on the solar disk.

Listen to the creepy sound of a strong solar flare!
