Excited Singaporeans were quick to snap photos and videos yesterday evening when a double rainbow was spotted in the Republic's skies.

From HarbourFront to Jurong, delighted Singaporeans shared photos of the phenomenon on social media, accompanied by cheerful captions and emojis.

In some cultures, double rainbows are considered signs of good fortune.

The phenomenon occurs when light reflects inside raindrops twice, creating a second spectrum across the sky. The second rainbow is often at a different angle from the first and features colours in reverse order. It also tends to be fainter than the first arc, which sometimes makes it hard to capture in photos.

A double rainbow was last seen in Singapore in July last year.
