Sky 'split' into 2 shades of blue

If you were out and about on Wednesday evening (Feb 13), you may have noticed a strange phenomenon in the sky.

Stomp contributors Lynette and Albert noticed the sky had been 'split' into two shades of blue and shared photos of what they saw.

Lynette witnessed the unusual sight in the sky over the Jurong area at about 7pm while Albert told Stomp he noticed it as he was driving from Tampines to Bedok Reservoir at around 7.10pm.

Albert said: "The sky appeared two have two colours, a darker side and a brighter side drawn by heaven with a line divider."

In response to a Stomp media query, a spokesman from Meteorological Service Singapore explained what caused the sky to look that way.

"The photos appear to show anti-crepuscular rays," he said.

"This is a meteorological optical phenomena usually visible around sunrise or sunset (when the sun is partially obscured).

"Anti-crepuscular rays are parallel shafts of sunlight that extend past clouds blocking the sun and are visible because of scattering of light by small water droplets or particles in the atmosphere."


These rays, called anti-crepuscular rays, originate at the sun, cross over the sky to the opposite horizon, and appear to converge toward the antisolar point because of perspective.

Crepuscular rays (more commonly known as sunbeams, sun rays, splintered light, or god rays), in meteorological optics, are rays of sunlight that appear to radiate from the point in the sky where the Sun is located.

Anti-solar (Anti-crepuscular) rays

Rays in the east opposite the setting sun the foreground and clouds are still sunlit. Leigh Hilbert caught these anti-crepuscular rays on 3rd March 2004 in Washington State.

Crepuscular rays appear to converge on the sun, anticrepuscular or antisolar rays converge in the opposite direction and you must have your back to the sun or sunset point to see them. They appear to converge towards the antisolar point, the point on the sky sphere directly opposite the sun. Like crepuscular rays they are parallel shafts of sunlight from holes in the clouds and their apparently odd directions are a perspective effect. Think of a long straight road, it converges towards the horizon but turn around and it also converges to the opposite horizon. Crepuscular and anticrepuscular rays behave in the same way.

Anticrepuscular rays are not rare but they must be sought carefully. When ordinary crepuscular rays are visible, turn around and search for their opposite numbers. More rarely, sunrays pass right across the sky.
