The breath-taking light display seen across the northern hemisphere in the early hours of Wednesday morning was caused by the biggest spike in solar activity for around two decades.

Met Office forecaster Craig Snell said: “It was the biggest solar flare that has come to earth in the last 19 to 20 years. There were reds and greens which lit up the sky.”
