A New Meteorite in Italy: the Fermo Chondrite

A stony meteorite fell in central Italy on September 25, 1996, at a site
(lambda=13deg 45min 12sec E, phi=43deg 10min 52sec N) close to a field,
3-4 km north-east of the town of Fermo and a few kilometers from the
Adriatic coast. The meteorite is one piece of 10.2 kg of stone and
exhibits the characteristic fusion crust. The body is classified as a
H3-5 chondrite breccia. Production in stony meteorites as Fermo, of
cosmogenic isotopes (22Na and 44Ti) by means of galactic cosmic rays,
offers a direct assessment of the solar activity at different time
scales (11-year solar cycle and century-scale variations).
