Bengaluru, India is set to witness a rare celestial phenomenon known as a “Zero Shadow Day” today, April 25. This unique event occurs twice a year at locations between +23.5 and -23.5 degrees latitude, where the sun is at its highest position in the sky and neither living nor non-living objects cast any shadows.
The Zero Shadow Day in Bengaluru will occur at precisely 12:17 pm, where none of the standing objects from the city will cast any shadow for a short period of time. According to the Archaeological Survey of India (ASI) website, this phenomenon happens when the sun’s declination is equal to the latitude of the location, twice a year during Uttarayan and Dakshinayan.
The Indian Institute of Astrophysics at Kormangala, Bengaluru, is set to host several events to mark this historic day. The ASI website notes that the Zero Shadow Day was last observed in Bhubaneswar, Odisha in 2021.
Residents in Bengaluru are excited to witness this rare event, which is expected to last for a few minutes. The Zero Shadow Day offers a unique opportunity to experience a rare celestial phenomenon and appreciate the wonders of the universe.
