The strong geomagetic storm surprised early risers yesterday on St. Patrick’s Day with a spectacular display of the northern lights, ended up with staying power. According to Spaceweather.com, a fast-moving CME hit Earth’s magnetic field that at first had little effect. But as Earth moved into the CME’s strongly-magnetized wake, the storm intensified until it became a G4-class event. “For more than 9 hours, it was the strongest geomagnetic storm of the current solar cycle,” and the glow of aurora was seen around the world — in the northern hemisphere, anyway — farther south than usual, such as in Kanasa and Virginia in the US and in Oxfordshire, Wiltshire and Hampshire in the UK.
Speaking of ‘around the world,’ astronaut Terry Virts took the Vine video above, from the International Space Station.
