112 years after the explosive Tunguska event of June 30th 1908, internationally commemorated as World Asteroid Day, a rock with an estimated mass of 100 grams blazed through the skies of Brazil. The event was captured by 4 cameras belonging to participants of the BRAMON network in Nhandeara and Patos de Minas, and by at least 4 cameras from the climaaovivo.com.br network and Icarus Brazil Project.
The prograde (SW to NE) bolide began its bright phase at 04:17 BRT (07:17 UTC) on June 30 at an altitude of 84.6 km above the municipality of Penápolis and soared northeast at 16.9 km/s until it disappeared at an altitude of 29.6 km over the municipality of Urupês. Although very bright, the analyses indicate that the bolide was generated by a small fragment of space rock with about 100 grams of mass that completely vaporized through it’s atmospheric passage.
