Multiple Geomagnetic Storms Expected to Hit Earth This Week, Scientists Say

A major solar eruption is shown in progress on Oct. 29, 2003. This X18 flare is the strongest flare since Aug. 16, 1989 when an X20 flare occurred.

The Space Weather Prediction Center issued a geomagnetic storm watch on March 13, noting that mild solar storms are expected to hit earth this week due to “possible effects from the arrival of coronal mass ejections on March 10.”

Geomagnetic storms occur when a large burst of solar wind interferes with the Earth’s magnetic field.
