AB On April 13, 2013 a very bright fireball with an absolute magnitude of -13:0  ± 0:5 was recorded over the center of Spain. Thissporadic event, which was witnessed by numerous casual observers throughout the whole country, was imaged from seven meteorobservingstations operated by the Spanish Meteor Network (SPMN), and its emission spectrum was also obtained in the frameworkof our meteor spectroscopy campaign. The atmospheric trajectory of the bolide and the heliocentric orbit of the parent meteoroid areanalyzed here. The spectrum reveals a chondritic nature for this particle, which was following a Jupiter family comet orbit beforeits encounter with the Earth. In addition, the emission spectrum of the meteoric afterglow was recorded during about 0.8 s. Themain emission lines appearing in this signal were identified and their evolution with time is also discussed. Afterglow spectra are notabundant in the literature, and these can provide important clues about the physical proceses taking place in meteoric persistent trains.
