No shadow day

It's said that your shadow is your most faithful companion. It never leaves your side. Not so, today. Don't be surprised if you don't see your shadow around noon on Wednesday, which is zero shadow day'. Explaining the phenomenon, Arvind Paranjpye, scientific officer at the Inter-University Centre for Astronomy and Astrophysics (Iucaa), said, "It occurs due to the northward and southward motion of the sun and when it is positioned at 23 1/2 degree altitude, the sun's rays appear exactly overhead around noon." The event occurs annually, but Wednesday will be an opportune time to witness the event, since it is summer, he added. (11 May 2012. Credit: Times of India and indigenus)
