SINGAPORE: An unusual rainbow hogged a limelight across Singapore with many people sharing its pictures of rare dazzling sight on the social media.

A fire rainbow is an optical phenomenon also known as circumhorizontal arc, according to a Facebook post by National Environment Agency (NEA) last April.

 

“They’re actually ice halos formed by the refraction of the sunlight (or occasionally moonlight) in plate-shaped ice crystals suspended in the atmosphere,” explained NEA.

A caller to Mediacorp’s news hotline, Mr Bob Toh, said the shape of the rainbow looked “like dolphins.” He was at Seletar Mall when he saw the rainbow.

 

 

A resident named Fazidah Mokhtar, who works in a childcare centre, told the BBC that she spotted it around 17:10 on Monday (09:10 GMT).

 

 

“It started as a small orange circle and then grew bigger and bigger till all the colours came out… It lasted for about 15 minutes and it slowly went off.

She informed “all the children in the school, some parents, and other staff were very excited and commenting that it was very, very rare to see such a beautiful and unique rainbow”.
