Spectral analysis and orbit of the

Abstract

The continuous monitoring of meteor and fireball activity provides helpful information about meteoroid streams, but also about the mechanisms that deliver these particles of interplanetary matter to the Earth [1, 2, 3]. Besides, by means of meteor spectroscopy we can obtain an insight into the chemical nature of meteoroids ablating in the atmosphere. Very bright fireball events are particularly interesting, as under appropriate circumstances they may give rise to meteorite falls. With this aim, the SPanish Meteor Network (SPMN) is performing a continuous meteor monitoring and spectroscopic campaign from 25 observing stations located in Spain. These monitor the night sky over the Iberian Peninsula and neighbouring areas. In this work we present the analysis of a mag. -9 sporadic fireball recorded over the Doñana Natural Park on Jan. 25, 2012.
