Atmospheric trajectory, orbit and chemical composition of a sporadic bolide imaged in 2011

Abstract

High-sensitivity CCD video devices are commonly employed to monitor meteor and fireball activity. These systems provide useful data for the determination, for instance, of radiant, orbital and photometric parameters [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]. Video spectroscopic techniques provide also very valuable data about the chemical nature of these particles of interplanetary matter [3, 5]. With this aim, The SPanish Meteor Network (SPMN) has systematically performed multiplestation video observations of major and minor meteor showers since 2006. In this work we analyze a doublestation sporadic fireball imaged in the framework of our continuous fireball monitoring and spectroscopic campaigns in 2011.
