Bengaluru folks will be able to observe a unique celestial event today, April 25, where vertical objects in the city will cast no shadow during noon. During the phenomenon, called Zero Shadow Day, the Sun will be directly overhead for a short time. On this day, the Indian Institute of Astrophysics (IIA), Bengaluru, is organising several events in its campus to mark the rare event.

“Come celebrate Zero Shadow Day #ZSD at our Koramangala campus on 25 Apr from 10 AM-1 PM. Sun will be directly overhead at 12:17,” the IIA tweeted.
