South Atlantic Mesospheric Airburst (cneos-fb-03)
At 2026-09-29 14:08:19 UTC, U.S. Government infrasound and geostationary lightning mapper sensors recorded bolide cneos-fb-03 entering Earth's atmosphere above (-21.40°, -14.80°). Traveling along an ECEF 3D velocity vector of (vx=14.2, vy=11.7, vz=-11.5) km/s (speed 21.80 km/s), hydrodynamic stagnation ram pressure peaked at 14.76 MPa at 29.4 km altitude, triggering catastrophic fragmentation with 5.44e+13 Joules radiated optical energy and 13.00 kilotons TNT total acoustic-kinetic yield.

Atmospheric Bolide Frequently Asked Questions
Where did CNEOS bolide cneos-fb-03 detonate in the atmosphere?
Bolide cneos-fb-03 reached peak aerodynamic breakup at 29.4 km altitude over signed coordinates (-21.40°, -14.80°) on 2026-09-29 14:08:19 UTC.
How is the 3D entry vector (14.2, 11.7, -11.5) km/s used in CesiumJS?
Meteors.ai converts the Earth-Centered Earth-Fixed (ECEF) velocity vector into a 3D atmospheric entry ray on our NASA GIBS WMTS globe, illustrating the exact entry azimuth and airburst altitude (29.4 km).
