A series of three powerful flares and associated explosions of solar material out across the Solar System have set Earth squarely in the path of a "severe"-level geomagnetic storm.

The sun unleashed a rare and powerful double eruption this week, sending two massive X-class solar flares from sunspot AR4274 hurtling toward Earth. The National Oceanic and Atmospheric Administration (NOAA) responded by issuing a G3 (Strong) geomagnetic storm watch for November 6–7,

Space weather forecasters are watching for faint CMEs that could reach Earth later this week. After more than three weeks without a powerful solar flare, the sun has suddenly ramped up its activity, firing off three M-class solar flares in less than 24 hours.

Sunspot AR3474 detonated with an X1.8 solar flare on November 4, sending an ultraviolet wave silencing South America's shortwave radio communications.
