Residents in the capital were treated to an awe-inspiring sight in the sky on Sunday when a phenomenon known as a 22-degree halo was visible at noon and well into the afternoon.
The halo appeared as a rainbow-like ring with limited colours, forming a circle around the Sun, with the inside of the ring noticeably darker than the horizon.
Toqueer Ahmed noticed the halo while outside at noon. "I walked to a different location thinking it was a reflection, but it still appeared as it is," said Mr Ahmed. "I live in Khalidiyah, I've been here eight years, I've seen lot of sunny days but nothing like this. It was very surprising, we were shocked when we saw it."
The halo is formed around the Sun or the Moon when light is refracted through tiny hexagonal ice crystals trapped within cirrus clouds.
The clouds are faintly visible to the eye, located between five and 10 kilometres high in the Earth's atmosphere.
The phenomenon was not visible in Dubai.
Halos around the Sun and the Moon were believed to be part of a primitive form of weather forecasting, and are sometimes observed before rainfall.
