Bhubaneswar (SunstarTV Bureau): Have you ever observed no shadow of yourself under Sun? If not, then wait for the rare and interesting event to happen today in Bhubaneswar when your shadow will be exactly under you.
There will be no shadow of any object when the Sun is at its zenith around noon. The Zero Shadow Days (ZSDs) can be observed in all parts of the State on different dates and times.
While the residents of Bhubaneswar can observe it at 11.43 am on Friday for 2 minutes long.
Deputy Director of Pathani Samanta Planetarium Subhendu Pattnaik said the ZSDs fall during the Uttarayan when the Sun moves northwards and Dakshinayan when the Sun moves southwards.
“The event can only be observed between Kanyakumari to central India below the line of Tropic of Cancer which passes through eight States – Odisha, Rajasthan, Gujarat, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal and Tripura,” he informed.
There are two ZSDs every year for every point on Earth between the Tropics of Cancer and Capricorn. The Tropic of Capricorn passes well below the Indian land mass whereas the Tropic of Cancer passes through central India little above Odisha.
It happens because Earth’s rotation axis is tilted at an angle of 23.5° to the axis of revolution around the Sun. The Sun’s location moves from 23.5° N to 23.5° S of Earth’s equator. All places whose latitude equals the angle between the Sun’s location and the equator will experience ZSDs.
