A halo around the sun was spotted in the sky over Trinidad and Tobago on Saturday.
The optical phenomenon was captured and shared to social media by many citizens.
What are sun halos?
According to the UK Met Office, halos require ice crystals to form - either from high cirrus cloud of free falling crystals.
It explained: "Typically sunlight or moonlight is reflected by ice crystals producing a white halo. However, if the light rays strike the light at a particular angle, some light may be refracted. In such situations the halo will have a faint colouration."
The UK Met Office added that the majority of ice crystals are hexagonal, or six-sided, and the most common angle of refraction through such a crystal is about 22 degrees.
It said this is the most frequent type of halo and they are named 22° halos.
