Thule High-Arctic Sector, Greenland (cneos-fb-greenland-2018)
At 2018-07-25 21:55:26 UTC, U.S. Government infrasound and geostationary lightning mapper sensors recorded bolide cneos-fb-greenland-2018 entering Earth's atmosphere above (76.90°, -69.00°). Traveling along an ECEF 3D velocity vector of (vx=11.2, vy=-18.5, vz=-11.4) km/s (speed 24.40 km/s), hydrodynamic stagnation ram pressure peaked at 3.25 MPa at 43.3 km altitude, triggering catastrophic fragmentation with 8.79e+12 Joules radiated optical energy and 2.10 kilotons TNT total acoustic-kinetic yield.
