According to eyewitness accounts and several media reports on the evening of September 14, 2011 at 21:00 GMT a bright bolide was observed by hundreds of observers in the department of Assaba, in south Mauritania. A terminal fragmentation and sound phenomena occured near the end point of the trajectory. At least one mass of 3.5 kg was seen to impact and recovered the morning after the fall near Bou Mdeid, ~ 60 km north of Kiffa. Gamma-ray spectroscopy conducted 84 days after the fall confirmed the recency of the event. Pictured above is the 1,453 g half individual that was broken from the intact 3.5 kg mass by the finder the day after the fall.
