- A strong solar eruption this week could produce a powerful geomagnetic storm on Friday.
- The storm — called a coronal mass ejection — is eating up stray energy in space as it heads for Earth.
- The storm could bring impressive displays of the aurora farther south than usual.
A series of strong solar eruptions this week could trigger a powerful geomagnetic storm by Friday, bringing incredible aurora displays farther south than usual.
Earlier this week the sun ejected a series of powerful eruptions called coronal mass ejections (CME), which happen when the sun's magnetic fields collide, causing an explosion that sometimes strikes Earth.
