Citizens in Nagpur witnessed the unique astronomical phenomenon of “Zero Shadow Day” on Tuesday, as the Sun appeared nearly overhead around noon, causing vertical objects to cast almost no shadow for a brief period. The phenomenon was expected to occur around 12:10 pm in the city.
Zero Shadow Day takes place twice a year in locations situated between the Tropic of Cancer and the Tropic of Capricorn. During this event, the Sun reaches its highest point in the sky at nearly 90 degrees above the horizon, resulting in shadows shrinking drastically and momentarily disappearing directly beneath objects.
Science enthusiasts, students, and astronomy lovers gathered to observe the rare occurrence by placing upright objects like sticks, bottles, and poles on flat surfaces to witness the disappearing shadow effect.
Astronomy experts explained that the event is caused by the Earth’s tilt and the apparent movement of the Sun. The phenomenon is visible only in tropical regions and cannot be experienced in places located north of the Tropic of Cancer.
Nagpur will witness the phenomenon once again later this year on July 17.
