Several Leonid fireballs were successfully photographed by the Japanese Fireball Network and by other observers in Japan on
16 November, 1996. A totals of seven of these were simultaneously observed from two or more stations, from which the orbital
and physical data were deduced. The radiant of these fireballs were very small, only 0.1°, similar to that of the 1991 Perseids.
The 1996 Leonids showed a lower magnitude distribution index similar to those obtained in the 1961 and 1965 Leonids. All of
these showers occurred before perihelion passage of the parent comet. We conclude that we have already encountered the elongated
front part of the dust trail of the Leonid parent comet, where the trail is probably composed of larger dust particles.
