At least four stones fell over a distance of about 9 km at the end of a west to east trajectory on 25 April I971 at about I63O hours local time. Their approximate location is 11° 51" N., 8° 13' E.  About I3.4 kg of this xenolithic bronzite chondrite, class H4, were recovered. A bulk chemical analysis with total Fe = 29.4 % (wt), is presented. Olivine is Fals.9 (molec.) in composition. Concentrations of the cosmogenic radionuclides 22Na, 26AI, and 54Mn were 71±6, 56±5 and 84±6 dpm/kg, respectively.
