Spectra and orbital analysis of an october delta aurigid fireball

Abstract

The SPanish Meteor Network (SPMN) is currently performing a continuous monitoring of meteor and fireball activity over the Iberian Peninsula and nearby areas by means of 25 observing stations. This coverage, together with favourable weather conditions in our country in comparison with other areas in Europe, is providing a huge amount of helpful information about the activity of major and minor meteoroid streams, but also about events with a sporadic origin. The analysis of events simultaneously imaged from, at least, two different locations allows for the determination of atmospheric trajectories, radiants and orbital data, but also the calculation of physicochemical parameters such as masses and tensile strengths [1, 2, 3]. Spectroscopic techniques provide also very valuable data about the chemical nature of meteoroids ablating in the atmosphere [3, 4, 5, 6]. As an example of our observational effort, we present here the preliminary analysis of a multi-station October δ-Aurigid fireball recorded in 2012
