We present the analysis of the atmospheric trajectory and orbital data offour bright bolides observed over Spain, one of which is a potential meteoritedropping event. Their absolute magnitude ranges from -10 to -11. Two of theseare of sporadic origin, although a Geminid and a kappa-Cygnid fireball are alsoconsidered. These events were recorded in the framework of the continuousfireball monitoring and spectroscopy campaigns developed by the SPanish MeteorNetwork (SPMN) between 2010 and 2012. The tensile strength of the parentmeteoroids is estimated and the abundances of the main rock-forming elements inthese particles are calculated from the emission spectrum obtained for three ofthese events. This analysis revealed a chondritic nature for these meteoroids.
