Aura a common phenomenon – Prof. Chandana Jayaratne

Apr 17, 2011 7:46:00 AM - itnnews.lk

Professor Chandana Jayaratne has said that the aura around the moon is a common phenomenon.

The aura that is being sighted around the moon is the result of the normal situation prevailing in the atmosphere. The ring around the Moon is caused by the refraction of Moonlight, which of course is reflected sunlight, from ice crystals in the upper atmosphere. The shape of the ice crystals results in a focusing of the light into a ring. Since the ice crystals typically have the same shape, namely a hexagonal shape, the Moon ring is almost always the same size. Professor Chandana Jayaratne said that the Aura around the moon that has been witnessed in the past few days will not have any effect on earth.
