Summary: At least four stones fell over a distance of about 9 km at the end of a west to east trajectory on 25 April 1971 at about 1630 hours local time. Their approximate location is 11° 51′ N., 8° 13′ E. About 13·4 kg of this xenolithic bronzite chondrite, class H₄, were recovered. A bulk chemical analysis with total Fe = 29°4 % (wt), is presented. Olivine is Fa_18.9 (molec.) in composition. Concentrations of the cosmogenic radionuclides ²²Na, ²⁶Al, and ⁵⁴Mn were 71±6, 56±5 and 84±6 dpm/kg, respectively.
