Analisys of a sporadic fireball recorded over Spain in 2012

Abstract

The SPanish Meteor Network (SPMN) is currently performing a continuous monitoring of meteor and fireball activity by means of 25 observing stations located in Spain. The analysis of events simultaneously imaged from, at least, two different locations provides information about meteoroids ablating in the atmosphere. In this way, atmospheric trajectories, radiant, orbital parameters and physicochemical parameters such as mass and tensile strength can be obtained [1, 2, 3]. Accurate orbital data are, for instance, of a paramount importance in order to infer information about the likely parent body of a given meteoroid stream [4]. Spectroscopic techniques provide also very valuable data about the chemical nature of these particles of interplanetary matter [5, 6, 7]. In this context, we present here the analysis of a doublestation sporadic fireball imaged from two of our stations on February 25, 2012 (Figure 1).
