104 km height toward to east-south-east and disappeared east side of Izu peninsula 19 km height.
Many observers reported this fireball nearby the capital city on Christmas eve even a midnight phenomenon.
This sparks fireballs became terminal explosion that estimated fragmentation to broken to some meteoroid pieces.
A few audio reports suggested the sonic boom produced.
Geocentric trajectory and orbit calculated that produced meteorite fell prediction using three observers' TV images on SonotaCo Network.
The initial velocity was rather fast 21 km/s as results, extremely bright emission indicate
that is most of initial mass was lost by ablation in atmosphere.
The expected maximum meteorite mass was 350 grams but fell in the west sea of Izu Oshima island.
However the small meteorite fragments may fall pressed by westerlies in north west coast area of Izu Oshima Island.
