标题： On the airbursts of large meteoroids in the Earth's atmosphere. The Lugo bolide: reanalysis of a case study

摘要： 1993年1月19日，一颗非常明亮的火球（峰值亮度-23）穿越了意大利北部的天空，最终在意大利艾米利亚-罗马涅地区的卢戈镇上空爆炸。 这次爆炸（释放了14千吨能量）产生了冲击波，被六个当地的地震站记录下来。 对现有数据的重新分析使我们提出假设，该陨石是一个多孔的碳质球粒陨石，其组成某种程度上类似于小行星253马蒂尔德。 显示英文摘要

摘要： 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.
