A spectacular ‘fire rainbow’ cloud phenomenon has been captured on camera lighting up the sky in Singapore.

The amazing sight was visible over the sovereign city-state for around 15 minutes on February 20, one witness told the BBC.


“It started as a small orange circle then grew bigger and bigger [until] all the colours came out … It lasted for about 15 minutes and it slowly went off,” explained a childcare worker Fazidah Mokhtar.

She added “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”.


Photos of other ‘fire rainbows’ captured in Jamaica and the US have previously been shared on social media.

The phenomenon is known as cloud iridescence,’s senior meteorologist Nick Wiltgen previously explained.


“In clouds, iridescence is a by-product of sunlight being diffracted by water droplets or ice crystals, causing the various wavelengths of light, which we see as colours, to emerge at different angles,” he said.

“As they reach the observer’s eye, the observer perceives a pattern of various colours as those different wavelengths reach his or her eye from distinct directions, rather than being jumbled together and appearing whitish.”
