  On January 19, 1993, a very bright bolide (peak magnitude -23) crossed the
sky of Northern Italy, ending with an explosion approximately over the town of
Lugo (Emilia Romagna, Italy). The explosion (14 kton of energy) generated shock
waves which were recorded by six local seismic stations. A reanalysis of the
available data leads us to the hypothesis that the meteoroid was a porous
carbonaceous chondrite, somehow similar in constitution to the asteroid 253
Mathilde.
