"Solar Flare Sparks Radio Blackout and Northern Lights Warning"

A solar radiation storm triggered by a solar flare has caused a polar cap absorption event, leading to enduring radio blackouts near the Earth's poles. The storm, affecting radio frequencies below 35 megahertz, is a result of ionization of the ionosphere by the solar flare's radiation. Such events may become more common as the sun approaches its solar maximum, with the current storm subsiding but the polar cap absorption event expected to last for several more days.
