Hokkaido Trench Bolide Event (cneos-fb-05)
At 2026-09-04 22:19:55 UTC, U.S. Government infrasound and geostationary lightning mapper sensors recorded bolide cneos-fb-05 entering Earth's atmosphere above (41.90°, 143.80°). Traveling along an ECEF 3D velocity vector of (vx=-9.8, vy=-13.4, vz=-6.7) km/s (speed 17.90 km/s), hydrodynamic stagnation ram pressure peaked at 8.15 MPa at 31.0 km altitude, triggering catastrophic fragmentation with 3.18e+13 Joules radiated optical energy and 7.60 kilotons TNT total acoustic-kinetic yield.

Atmospheric Bolide Frequently Asked Questions
Where did CNEOS bolide cneos-fb-05 detonate in the atmosphere?
Bolide cneos-fb-05 reached peak aerodynamic breakup at 31.0 km altitude over signed coordinates (41.90°, 143.80°) on 2026-09-04 22:19:55 UTC.
How is the 3D entry vector (-9.8, -13.4, -6.7) 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 (31 km).
