On December 26, 2025, at 14:08:22(UT), a bright fireball was observed flying over Fukushima Prefecture.
The luminous images of the fall was captured by automatic meteor TV cameras operated by Mr.SonataCo (Tokyo pref.), Mr.C. Shimoda (Nagano pref.),
Mr.Y. Tonomura (Miyagi pref.), Mr.ts007 (Saitama pref.), and Mr.D. Fujii (Kanagawa pref.), and the data was submitted to the SonataCo Network.
From this, Mr.M. Ueda calculated the orbit.
The detail was described on the SonotaCo Network bulletin board
The atmospheric entry velocity was 22.08 km/s, and the ending point altitude, where it slowed to about 5.3 km/s, was 23.7 km.
The trajectory was a high angle of 84 degrees, nearly perpendicular to the ground, and the glow lasted for 4.1 seconds.
As a result of the high angle of entry, it can be assumed that the shock wave did not reach the ground.
The footage showed the object shattering, with several pieces spilling out as it emitted light.
The area where the meteorite is estimated to have fallen is a mountainous region in Minamiaidu Town, Minamiaidu District, Fukushima Prefecture.
Due to the weak westerly winds for winter and the high fall angle, the area where the rain is forecast to fall will be limited to a small area.
The estimated falling mass is estimated to be less than 200g, which is small considering the low altitude of the vanishing point.
The reason for this is that the penetration speed was high and the penetration angle was large, resulting in a high wear rate.
Since there was no major fragmentation, it is estimated that one major piece fell.
