Hello All again!

Tsukuba - H5-6 - brecciated - shock veins:

After a luminous meteor and violent detonations, 23 stones totalling
about 800 g (largest 177.5 g) were recovered, including one that
penetrated a roof.

In the late afternoon (about 16:20, Japanese Standard Time) on January
7, 1996, a meteorite shower fell around the city of Tsukuba, Japan (36
03.8 N/140 08.7 E) after the appearance of a luminous fireball,
violent detonations, and several explosions. Stones have been recovered
from 23 places, scattered in a triangular area with sides 6-8 km long.


Best wishes,

Bernd
