At 25, Feb. 2011,15h20m31s(UT), a fireball flights over west Kanagawa prefecture with a high elevation angle to north-west-north direction.
This fireball was taken by Sambonmatsu high school(Kagawa prefecture), Mr.T.Sekiguchi(Saitama Pref.), and Mr. SonotaCo(Tokyo) automatic TV camera.
Mr.O.Takahashi(Kanagawa Pref.) also taken by automatic fisheye camera.
Each observers analyzed automatic TV camera images by UFOAnalyzer and after, Mr. M. Ueda calculated orbit and physical parameters.
Y. Shiba(author) analyzed Mr.Takahashi's image.
It is a strange small orbit meteorite that has inner aphelion of the Mars orbit.
Fireball's deceleration was not recorded till 40 km altitude but rapidly decelerated on the terminal trajectory.
All images are not good resolution, so no fragmentation was found in all of the luminous paths.
The maximum luminous magnitude is -4. The end height is a low 24 km altitude. These suggest meteorites fell.
However mass loss was thought rapid near the end of the trajectory, so only a little mass 50g meteorite would be falling.
