Towada Meteorite

Return buck to Meteorite List

At spring(Apr.?), 1997(?) a manager of "tatami" mat shop found a hole of eaves in warehouse.
A stone was found under the hole and after kept.
S.Yoneda(National Science Museum, Tokyo) researched the stone as meteorite at 2001.
The meteorite fell time estimated at about 1985 from results of meteorite research and warehouse history.
4 cm length ordinary chondrite surface suggest fragmentation in atmosphere.
Other fragments would fall around some km area.
