Bengaluru residents to witness 'Zero Shadow Day' tomorrow
What's the story
Residents of Bengaluru will have the opportunity to witness a unique celestial event known as "Zero Shadow Day."
This fascinating occurrence is scheduled to take place between 12:17 pm and 12:23 pm.
During this time, the sun will be positioned directly overhead, resulting in the disappearance of all shadows.
The rare phenomenon will also be observed in other cities including Kanyakumari, Bhopal, Hyderabad, and Mumbai.
Celestial mechanics
Zero shadow day occurs in areas near the equator
The "Zero Shadow Day" phenomenon typically occurs in areas near the equator where the sun's angle is almost perpendicular to Earth's surface, causing objects to appear shadowless.
This event is due to Earth's orbit around the sun, which alters its sky position and results in varying seasons.
The Astronomical Society of India states that this event happens twice a year in locations between latitudes +23.5 and -23.5 degrees.
Public engagement
In Bengaluru, 'Zero Shadow Day' is typically observed around April
In Bengaluru, "Zero Shadow Day" is typically observed around April 24/25 and again on August 18 each year.
The Indian Institute of Astrophysics (IIA) in Bengaluru has organized events at its Koramangala campus to celebrate this day.
The public is invited to participate in activities from 10:00 am to 1:00 pm that involve observing and measuring changing shadow lengths of objects.
