Space Weather
The Sun emitted an Earth-directed coronal mass ejection (CME) one day before the summer solstice, which is when the Sun reaches its northernmost point in the sky. This particular solar phenomenon ejects billions of tons of particles into outer space that can impact our planet several day later.
The CME exited the Sun at speeds of approximately 1350 miles per second, which NASA says is very fast for CMEs.
These particles cannot pass through the Earth’s atmosphere to affect humans, but they can impact communication systems. Magnetic storms can disrupt communication signals and lead to surprising electrical surges in power grids.
Skywatchers in northern latitudes can expect spectacular northern lights in the coming days.
