Wednesday marks Zero Shadow Day in Bengaluru and it is being celebrated at the Jawaharlal Nehru planetarium in the city.
On a Zero Shadow Day, there will be almost no visible shadow seen at 12:18 pm sharp in Bengaluru. This is because the sun will be at its zenith on top of the city.
The phenomenon occurs twice a year as the sun traces its path to the Tropic of Cancer and then retraces its path towards the south.
Usually, the sun transits by small margins towards the north or south around noon. But on Zero Shadow Day, it will be exactly overhead.
The Jawaharlal Nehru Planetarium in the city is celebrating Zero Shadow Day by observing it and organising a workshop.
“We had about 50 students for the workshop and about 400 people who came to the planetarium to observe the Zero Shadow Days last year. We have also done various trial runs to ensure that everything goes smoothly,” said Pramod Galgali, the director of Jawaharlal Nehru Planetarium, told the Deccan Herald.
The workshop is being organised for students studying in Class 8 and higher to understand the science behind the phenomenon.
Zero Shadow Day will also be observed in Chennai at 12:07 pm. It can also be observed in other cities like Mangaluru, New Delhi and Jaipur, although the timings may vary.
