A bright daylight fireball was recorded at 17:49 UTC (14:49 LT) on September 9, 2025, over the Atlantic Ocean, off the northeastern coast of Brazil. NASA's CNEOS data show the object released 0.44 kilotons of impact energy at an altitude of 24 km (15 miles). IMO and AMS received 10 reports from Ceará, with witnesses describing orange to blue colors, persistent trails, fragmentation, and sounds ranging from faint hissing to thunder-like booms.

The event is confirmed by instrumental detection, satellite imagery, and eyewitness accounts, consistent with a low-altitude bolide airburst visible in broad daylight across Ceará.

A bright daylight fireball was recorded at 17:49 UTC (14:49 local time) on September 9, over the Atlantic Ocean, off the coast of Ceará State, northeastern Brazil. The event was registered at coordinates 2.3°S, 39.5°W.

NASA's Center for Near-Earth Object Studies (CNEOS) measured the object at a peak altitude of 24 km (15 miles). Its velocity was calculated at 20.7 km/s (74 520 km/h or 46 300 mph). The total radiated energy was 1.53 x 10¹¹ J, corresponding to an impact energy of 0.44 kilotons TNT equivalent.
