↑ What are Solar Storms?

By Doron Tal, 4X4XM

Solar storms are disturbances on the Sun that result from high-energy particles being released in explosive bursts away from the Sun. While they aren't dangerous for humans on the ground, they can cause disruptions to satellites and electronic devices.

During solar storms, the sun emits huge bursts known as solar flares

and coronal mass ejections (CMEs).
Solar flares are electromagnetic radiation that travels at the speed of light, reaching Earth in about eight minutes and twenty seconds.

CMEs, on the other hand, are massive bursts of energetic charged particles traveling at high speed.

Solar storms can affect technology like satellites, GPS systems, and radio communications, causing disruptions like GPS navigation in 2017 and a nine-hour blackout in Quebec in 1989. Although not directly threatening humans, their impact on technology and infrastructure is significant.
