The Leonid meteor shower takes place in the early hours of Saturday (18), with a peak at 1 am, and an even more intense flow between 3 am and 5 am.
The phenomenon occurs annually and can be seen from all over Brazil, especially away from urban centers and in cloudless places, where the sky will be clearer, allowing the phenomenon to be observed with the naked eye.
The rain is the result of the movement of comet Tempel-Tuttle, the parent body of the Leonids, which will cross Earth’s orbit, creating a vaporizing rain of debris in the atmosphere.
The comet takes 33 years to complete one orbit of the sun, and as it passes, it leaves a cloud of debris, which eventually reaches the Earth’s atmosphere, according to the rotational movement of our planet in the Solar system.
Typically, there are between 10 and 15 meteors per hour, and three or four fireballs per minute during the phenomenon.
This year’s event is not expected to produce a meteor storm, when it is possible to see more than 1,000 meteors per hour in the sky. This type of phenomenon was last noticed in 2001.
To photograph the meteor shower, NASA suggests using a manual focus camera on a tripod with a shutter release cable or built-in timer, equipped with a wide-angle lens.
