The aurora borealis in the sky over Great Chishill Windmill (Image: John Goodwin)
Royston resident John Goodwin captured this stunning photo of the aurora borealis over Great Chishill Windmill.
John spotted the natural phenomenon - also known as the northern lights - from his back garden, and headed out to get the windmill shot.
The lights were visible over the weekend following a G4 geomagnetic storm warning - the second highest warning on the scale which was last issued in 2005.

The sun produced solar flares, resulting in five outbursts of plasma capable of disrupting satellites in orbit and power grids on Earth.
Powerful eruptions known as coronal mass ejections led to the storm, which triggered the displays of the aurora.
The aurora is usually more likely to be visible in northern parts of the UK.
