In mid-January, the sky over large parts of the county, and the country, was lit up by a shimmering aurora borealis.

Social media was filled with photos of the green light phenomenon when thousands of people were amazed to see it for the first time.

On Thursday night, almost a month later, it was time again.

The light phenomenon occurs when charged particles from the sun reach the Earth's atmosphere where they collide with molecules and atoms which are then also charged.

Meanwhile, these return to their normal state to give the particles different colored light.
