A solar flare could significantly impact human life on Earth, such as creating geomagnetic storms and interrupting internet connection.

Furthermore, an intense solar storm creates temporary radio blackouts on the sunlit side of Earth.

According to the Spaceweather.com website, the last week’s solar flare caused a shortwave radio blackout over the Americas.

Mariners and radio operators may have noticed a signal loss at frequencies below 30 MHz for more than one hour.
