Meteor Airburst over NE China

2026, May 21. China, Heilongjiang, Shuangyashan, Baoqing County, Dongxing Town. Airburst. Time: 02:15:51UT. Coordinates: (46.6N;133.1E). Altitude: 31.5km. Velocity Components: vx =14.4; vy = -6.5; vz = 1.0. Absolute Velocity: 15.83 km/s. Angle of Entry: 3.62° relative to the horizontal plane. Note on the trajectory: Because the vertical component (v_z = 1.0) is very small compared to the horizontal speed (15.80 km/s), this meteor entered at an incredibly shallow, skimming angle—essentially a "grazing" fireball entry. Energy: 3.5e10, -e = 0.12 or 120,000 kg/TNT. Even though overland, I'm watching this region since the Arafura Sea meteoroid entry, and recent fireball entries over the Tasman Sea - see posts below.
