Ordinary chondrite (L6; S2)
Fell, 2 June 1843; 9.7 kg, 2 stones

After detonations a 7 kg meteorite was observed to fall 5 km east of Utrecht. Three days later a second 2.7 kg stone was recovered 3 km away at Loevenhoutje. A black fusion crust covers most of the stones and internal veins are present. Composition of olivine (Fa24) and low-Ca pyroxene ('hypersthene') indicate membership in the L (low bulk iron) ordinary chondrite group. The predominate olivine and orthopyroxene are accompanied by accessory Fe-Ni metal, troilite, plagioclase, and Ca-rich clinopyroxene. Small amounts of chromite are also reported. Extensive mineralogical studies are quite sparse in recent decades.

Utrecht is one of 269 ordinary chondrite falls listed exactly as an 'L6' chondrite. It is one of only 4 witnessed meteorites falls to have been recovered in the Netherlands. Two of the other Netherlands falls are also low iron ordinary chondrites (Uden [LL7] and Glanerbrug [L/LL5]).

Through 2000 most of the mass had been kept at the National Museum in Budapest with an additional 2.7 kg stored at Utrecht University.
