Physico-chemical properties of sporadic meteoroids inferred from de continuous monitoring of meteor and fireball activity

Abstract

Sporadic meteoroids make up the bulk of the meteoroids striking the Earth. The combined action of gravitational and radiation forces have reduced the coherence of the initial orbits of these particles to such a degree that they have become so diffuse as to be no longer recognizable as streams and merge them together into the sporadic meteoroid complex. The development of a continuous meteor and fireball monitoring campaign is fundamental to characterize the physico-chemical properties of sporadic meteoroids. In this context, we present here the preliminary analysis of a sporadic bolide simultaneously imaged in July 2012 from two meteor observing stations operated by the SPanish Meteor Network (SPMN).
