Abstract

On May 30, 2017, at about 21 h 09 min 17 s UTC a green bright fireball crossed the sky of northeastern Italy. The fireball path was observed from some all-sky cameras starting from a mean altitude of $81.1 \pm 0.2$ km (Lat. $44.369^{\circ } \pm 0.002^{\circ }$ N; Long. $11.859^{\circ } \pm 0.002^{\circ }$ E) and extinct at $23.3 \pm 0.2$ km (Lat. $45.246^{\circ } \pm 0.002^{\circ }$ N; Long. $12.046^{\circ } \pm 0.002^{\circ }$ E), between the Italian cities of Venice and Padua. In this paper, on the basis of simple physical models, we will compute the atmospheric trajectory, analyze the meteoroid atmospheric dynamics, the dark flight phase (with the strewn field) and compute the best heliocentric orbit of the progenitor body. Search for meteorites on the ground has not produced any results so far.
