Powerful M9-class Solar Flare Erupts --Hurling a Cloud of Plasma Toward Earth
Earthlings may see exceptional auroras from a strong solar flare that ejected a cloud of plasma toward Earth an Aug. 2, when an intense magnetic event above sunspot 1261 blasted out a flow of charged particles, according to SpaceWeather.com, a website that monitors space weather.
The event could unleash a geomagnetic storm here on our planet that might disrupt satellite and radio communications.
Skywatchers at the northern latitudes can expect extra-special aurora borealis displays, from the interaction of these charged particles with Earth's magnetic field.
