On February 18, 2019 at 10:00 UTC, 13:00 in local time, there was a superbolide hits Zambia in Africa. To date, there have been no reports of people seeing such an event, but was recorded by the international network of infrasound sensors administered by the US government. Acoordind with data of JPL/NASA the superbolide exploded releasing about 4.2 kilotons of energy (1/4 of the energy released by the Hiroshima bomb in World War II) at just 26 km height. The scientific society only learned of the event after JPL/NASA published the report.
Below is the estimated trajectory of the bolide.
The analysis of the trajectory of the event was made by Carlos Augusto Di Pietro, member of BRAMON. Di Pietro points out that possibly the bolide has left hundreds of kilograms of meteorites on the ground in that region. This is the fourth event analyzed by BRAMON that may have left meteorites in ground only in this February month.
In addition to this super bolide, there are reports that, a few hours later that day, another bolide was spotted by residents of the island of Mayotte less than 2,000 km from the super bolide as shown by AMS (https://fireball.amsmeteors.org/ members / imo_view / event / 2019/801? fbclid = IwAR08eR9EFf9NKUgTYSyX79pga23tfcgzDP4WCxJdPlyxxep5Uy19mBlo8wQ). Regarding this last event, for the moment we can not analyze due to the few data so far collected.
