Residents of Bengaluru can walk without shadows tomorrow because to a unique celestial occurrence. Everything you should know about Zero Shadow Day
Bengaluru locals will be able to witness “Zero Shadow Day,” a unique celestial occurrence, on Wednesday, April 24. The disappearance of shadows is a rare astronomical phenomenon that is predicted to happen tomorrow between 12:17 and 12:23 p.m.
There will be locations experiencing the zero shadow phenomenon that are similar in latitude to Bengaluru, India.
How can Zero Shadow Day occur?
On Zero Shadow Day, a rare occurrence in the sky, the sun exactly aligns overhead, eliminating shadows from vertical objects.
On Zero Shadow Day, when the sun is directly overhead at its highest point in the sky, there is no shadow cast on the ground.
In areas between the Tropics of Cancer and Capricorn, this occurrence happens twice a year.
This annual phenomenon takes place in Bengaluru, which is situated at a latitude of roughly 13.0 degrees north, on April 24 or 25, and August 18.
“For people living between +23.5 and -23.5 degrees latitude, the Sun’s declination will be equal to their latitude twice – once during Uttarayan and once during Dakshinayan,” reads the Astronomical Society of India website. The Sun will be precisely overhead at noon on these two days, meaning that no object on the ground will be shadowed.”
According to Britannica, declination is the angular distance a planet has north or south of the celestial equator.
The zero shadow days vary depending on where you live in the world.
The Indian Institute of Astrophysics in Bengaluru will hold events at its Koramangala campus to spread knowledge about this astronomical phenomenon. It has invited the students, teachers and astronomy enthusiasts to engage in hands-on activities from 10 am to 1 pm. The activities include observing the changing shadow lengths of objects and measuring them.
