L. Foschini, ON THE AIRBURST OF LARGE METEOROIDS IN THE EARTHS ATMOSPHERE - THE LUGO BOLIDE - REANALYSIS OF A CASE-STUDY, Astronomy and astrophysics (Berlin), 337(1), 1998, pp. 5-8
On January 19, 1993, a very bright bolide (peak magnitude -23) crossed
the sky of Northern Italy, ending with an explosion approximately ove
r 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 hypothes
is that the meteoroid was a porous carbonaceous chondrite, somehow sim
ilar in constitution to the asteroid 253 Mathilde.
