SINGAPORE (CNA) – A sun halo was seen from several locations in Singapore at around noon yesterday.
In a Facebook post, the National Environment Agency (NEA) said that a sun halo is not a common sight in Singapore, as they tend to be covered by low to mid-level clouds.
“Sun halos typically occur when high-level clouds are blown over the island from the immediate surroundings under favourable wind conditions,” said NEA.
“These faint coloured rings encircling the sun are formed by the refraction of the light through ice crystals in high-level clouds under relatively clear conditions.”
CNA readers sent in several images of the rainbow ring around the sun.
A CNA reader who identified herself as Lynne said she was having lunch in the City Hall area when she saw the halo.
“I couldn’t stop staring at it. It was just too beautiful. Photos don’t do justice to it,” she said.
CNA reader Chew Kok Kiong said he saw the halo from the window of an apartment in Jalan Hang Jebat at Queenstown.
“The shape was perfect with unblocked view and the cloud also shaded the sun partially,” he said. CNA reader Mark Rodel dela Rosa said he had just finished lunch in Tampines West at about noon when he saw other people looking up at the sky.
“At first I thought there’s some aircraft passing by. But when I checked it myself I saw an almost perfect rainbow surrounding the sun,” he said. The phenomenon lasted for about 20 minutes, he said, adding that he was “pretty amazed” as it was the first time he had seen a sun halo in Singapore.
