Most powerful solar storm in 6 years caused auroras all over the US. And nobody saw it coming

[Still Waters]

The strongest solar storm to hit Earth for six years sparked stunning auroras across the U.S., with intense light displays appearing as far south as Alabama and Northern California. Yet no one saw it coming. 

The March 24 solar storm was the result of a "stealth" coronal mass ejection (CME) – or a gargantuan, fast-moving blob of plasma and magnetic field released from the sun –  Live Science’s sister site Space.com reports. The CME came from a coronal hole wider than 20 Earths that was spewing out solar winds at speeds over 1.3 million mph (2.1 million km/h). 

Tamitha Skov, a U.S. space weather forecaster, told Space.com that no one saw the G4 storm coming because it was "nearly invisible." She said these stealth storms launch far slower than a typical CMEs that erupts, so are more difficult to observe.
