Around 10 to 15 meteors per hour are expected to be seen on November 20 (as earth will encounter dust trails of 1400 AD passage of the parent comet 55P/Tempel Tuttle), as per the International Meteor Organisation (IMO).
From 2.30 AM onwards, observers should look towards East direction to observe fast moving bright streaks of light zipping across the skies.
The meteor shower gets the name "LEONIDS" because meteors in it appear to radiate from the constellation Leo, Sri N Raghunandan Kumar of Planetary Society of India said.
Leonids have double peak activity as the number of meteors maximise on two dates that is on November 17 and 20.
Telescopes or binoculars are not required to witness this celestial spectacle, he said.
