Sunset with a difference: This dazzling halo was taken in Stockholm, Sweden,

This amazing sunset with a difference is a phenomenon than can arise when you view the sun through millions of ice crystals.
As water freezes in the upper atmosphere, millions of small, six-sided ice crystals - known as diamond dust - flutter to the ground.
And at the approach of either sunrise or sunset, this is what an observer passing through the same plane as the falling crystals will see.
Each crystal acts like a miniature lens, refracting the eye's view of sunlight and creating the phenomena known as sundogs.
The dramatic effect is also referred to a mock sun or a phantom sun.
This sun halo image was taken in Stockholm, Sweden, with the sun in the centre while two bright sundogs glow prominently from the left and the right.
Also visible is a bright 22 degree halo - as well as the rarer and much fainter 46 degree halo - also created by sunlight reflecting off atmospheric ice crystals.
Sundogs can be seen around the world as long as the conditions are suitable.
