Singapore's social media sphere was set abuzz after pictures of a double rainbow spotted over various areas of Singapore was shared online.

After a brief mid-day shower, the double rainbow was seen in the skies from various places, including northern and central Singapore.

Double rainbows have been seen over Singapore previously, but social media has made sharing such pictures a lot more common.

The rainbow is viewed as an auspicious symbol. According to the Bible, it was a symbol of God's covenant with Noah not to flood the earth and destroy mankind on a global scale again, after the Great Flood in Biblical records.

In Chinese belief, a double rainbow is considered an auspicious symbol.

According to Wikipedia, it was the Greek scholar Aristotle who first noticed the phenomenon of the rainbow, and Isaac Newton the scientist who demonstrated that white light was composed of all colours of the rainbow.

Double rainbows are caused by a double reflection of sunlight inside the raindrops, and are centred on the sun itself. Since they are about 127° (violet) to 130° (red) wide, they are seen on the same side of the sky as the primary rainbow.

The secondary rainbow is fainter than the primary because more light escapes from two reflections compared to one and because the rainbow itself is spread over a greater area of the sky.
