Spotted this interesting report about a rare natural phenomenon in the NST today.
LANGKAWI, MON:
The sudden appearance of a solar halo (also known as the parhelic circle) above the skies of Langkawi today caught the attention of participants at the Langkawi International Dialogue (LID) as well as members of the media.
Dozens of photographers covering LID hurriedly snapped away at the halo encircling the sun at about 2.40 pm, before it disappeared about 20 minutes later.
The photographers were not the only ones captivated by the phenomenon.
Works Minister Datuk Seri S. Samy Vellu, who is here attending LID, was also among the crowd of onlookers admiring the rare sight.This phenomenon similar to a rainbow, except it is formed by the refraction of sunlight through ice crystals, instead of raindrops suspended in the air. The ice crystals are from cirrus clouds and have to be of the type with a large radius for the phenomenon to take place.
There must also be no wind and the sun has to be at an altitude of less than 34 degrees for the halo to to occur.
