NASA warns of potential solar storm and blackouts on Earth.

An M7-class solar flare eruption from sunspot AR3288 caused a radio blackout over the Atlantic Ocean region, according to NASA. The explosion ionized the top of Earth's atmosphere, disrupting radio transmissions below 20 MHz for up to 30 minutes. The bigger concern is whether a solar storm event will follow, which can disrupt GPS and mobile networks, hamper internet connectivity, damage satellites, cause power grid failures, and even corrupt ground-based electronics. However, no conclusive evidence for an incoming solar storm was recovered, and more clarity is expected over the next two days.
