An incredibly bright fireball was seen crossing the Tquiona sky last Thursday (02), before exploding in the atmosphere with a force equivalent to 150 tons of TNT. Observers report a glowing fireball, which lit the sky with purple-green light, followed by a crash that was probably a single noise generated when an object breaks the sound barrier.
The event took place at 02:32 in the morning (local time, 14:32 on the 1st of July in Brasilia time), and was visible in most of the Kanto region, which in addition to the capital includes the prefectures of Gunma, Tochigi, Ibaraki, Saitama, Chiba and Kanagawa.
According to the International Meteor Organization (IMO), the object was a meteor about 1.5 meters in diameter, which entered the atmosphere at 15 km / s (54 thousand km / h) and weighed 5.5 tons. The explosion was strong enough to be recorded by infrasound monitoring stations, created to detect nuclear tests, more than 2,000 km away.

As the meteor exploded at a high altitude, there is no record of damage. Despite being brilliant, the rock that caused the phenomenon can be considered “small”. For comparison, the Chelyabinsk meteorite, which caused destruction in Russia in 2013, was 10 to 20 times larger.
