A fireball with an impact energy of 0.38 kilotons (380 tons of TNT equivalent) was detected at 22:26 UTC on September 13, 2025, at an altitude of 22.8 km (14.2 miles) over central Argentina. The event was observed from multiple provinces and produced a persistent trail and visible fragmentation.
A bright fireball was detected at 19:26 local time (22:26 UTC) on September 13, over central Argentina.
The object entered the atmosphere near latitude 38.0°S and longitude 64.8°W, at an altitude of 22.8 km (14.2 miles), releasing an estimated 0.38 kilotons (380 tons of TNT equivalent) of energy, according to NASA’s Center for Near Earth Object Studies (CNEOS).
The International Meteor Organization (IMO) received two reports submitted from observers in Bahía Blanca, Buenos Aires Province, and Puerto Madryn, Chubut Province.
Observers described the fireball as exceptionally bright, with magnitudes between −5 and −6. One report noted a white terminal flash with fragmentation and a persistent incandescent trail lasting about 90 seconds. Another described a large explosion-like flash and a red cloud that remained visible for several minutes.
This event comes just four days after another bright fireball over northeastern Brazil. On September 9, a daylight bolide was recorded at 14:49 local time (17:49 UTC) over the Atlantic Ocean, off the coast of Ceará State. According to NASA CNEOS, that object released 0.44 kilotons of energy at an altitude of 24 km (15 miles).
The American Meteor Society (AMS) and IMO received 10 reports from witnesses across Ceará, who described colors ranging from orange to blue, persistent trails, fragmentation, and sounds varying from faint hissing to thunder-like booms. Satellite imagery confirmed the atmospheric flash.
Fireballs of this scale occur several times each year worldwide. With an energy release under 1 kiloton, they typically disintegrate at high altitudes and pose no hazard to the surface.
