What is the truth behind the appearance of three suns in the sky of China?
A video clip accompanied by news stating "the appearance of three suns in the sky of China" was circulated on social media.
Clarification
The video refers to a phenomenon called the Sun Dog or Sundog, known scientifically as (parhelia).
It is an optical illusion phenomenon that occurs in the atmosphere at certain temperatures due to the refraction of sunlight on ice crystals present in the atmosphere. This phenomenon usually has faint colors appearing at the same altitude as the sun's horizon, and bright light spots may appear, making it seem like there are two additional suns in the sky.
The phenomenon is named Sundog, referring to hunting or tracking, as the shapes accompany the sun like a dog follows its owner.
Although this phenomenon is uncommon, it has occurred in previous years in different regions.
