Alderney residents were treated to a display of the Northern Lights on Monday night, as the year’s strongest display so far reached as far as northern Italy.

The phenomenon, also known as the Aurora Borealis, is caused by charged particles from the sun hitting the atmosphere around the north pole, making it glow.

  • Dark purple aurora over the island of Alderney.
  • Red and mint green Aurora behind a different tree.
  • Red and lime green Aurora behind a tree.
  • Red and lime green Aurora behind a lighthouse.

While many people in Guernsey could only catch a few glimpses because of cloud cover, Express readers in the Bailiwick’s second-largest island got a magnificent display of lights.

The lights are a frequent occurrence in the arctic circle, but are not normally seen so far south.

However, a coronal mass injection – when the sun spits out large numbers of particles – meant they could be seen much further south than normal.

The Met Office said the lights “may still be visible” on Tuesday night (20 January) as well.
