This video shows the moment a young man captures a rare phenomenon called a sun halo.

A Twitter user going by the name of @Bnguyen24 panned his camera towards the sky above a palm tree-lined street in Malaysia to show the blazing sun with a huge ring around it.

One user reacting to the video, said: 'I saw this in Cuba and thought the world was ending.'

The deep freeze gripping the Midwest of America also created the spectacle - also known as 'sun dogs' - thousands of miles away from Malaysia.

As temperatures plunged as low as -42F in Park Rapids, Minnesota and -31F in Fargo, North Dakota, sun dogs were spotted throughout the upper Midwest on Tuesday and Wednesday.

The National Weather Service in the US describes the phenomenon as colored spots of light that appear on either side of the sun due to the refraction of light through ice crystals.

They are located approximately 22 degrees either left, right, or both, from the sun, depending on where the ice crystals are present.

The colors usually go from red closest to the sun, out to blue on the outside of the sundog.

Sundogs are also known as mock suns or parhelia, which means 'with the sun'.

The National Weather Service (NWS) confirmed sightings of both sun dogs and 'halos' in Sioux Falls, South Dakota, on Tuesday morning.

On Twitter, photos of the phenomenon also poured in from North Dakota and Iowa.

The painfully cold weather system that put much of the Midwest into a historic deep freeze was expected to ease today, though temperatures could still tumble to record lows in some places before the region begins to thaw out.
