Analisys of a superbolide observed over the Iberian Peninsula on July 21, 2012

Abstract

A superbolide was observed on July 21, 2012 over the center and south of Spain. The event was recorded in the framework of our continuous fireball monitoring and spectroscopic campaigns. Besides, because of optimal weather conditions, the bolide was imaged from ten meteor observing stations operated by the SPanish Meteor Network (SPMN). These employ high-sensitivity CCD video cameras and spectrographs to monitor the night sky. In this way, different physico- chemical parameters of meteoroids ablating in the atmosphere can be calculated [1, 2, 3]. We present here a preliminary analysis of this multi-station fireball, which was imaged together with its emission spectrum.
