Halo, what a rare sight


A halo around the sun, viewed from the vicinity of the Singapore Flyer, was seen in the skies over Singapore on Tuesday afternoon. A halo is a rare optical phenomenon that appears near or around the sun, and is formed when sunlight is refracted by ice crystals suspended in cirrus clouds in the upper atmosphere. Before modern forms of meteorology were developed, atmospheric phenomena such as haloes were used as an empirical means of weather forecasting.
