Analisys of large sporadic meteoroids in the framework on the Spanish meteor network

Abstract

The monitoring of very bright fireball events is one of the aims of the SPanish Meteor Network (SPMN), as these allow us to collect very valuable information on the origin and properties of large meteoroids that can give rise to the relatively rare potential meteorite-dropping bolides. Thus, one of the main goals of our meteor network is the analysis of the physico-chemical properties of these meteoroids from multiple station data, as a continuous monitoring of the night sky can provide useful data to improve our knowledge of the mechanisms that deliver these materials to the Earth. In this context, we have imaged on October 13, 2009 a double-station sporadic fireball with an absolute magnitude of about -10±1. The analysis of this event is presented here.
