AB High-sensitivity CCD video camerashave been commonly used for the study of theactivity of meteoroid streams. These provide usefuldata for the determination, for instance, of radiant,orbital and photometric parameters [1, 2, 3]. Thesedevices can also be used to record emission spectra ofmeteoroids ablating in the Earth's atmosphere whenholographic diffraction gratings are employed [3].The SPMN is currently performing a continuousmonitoring of meteor activity by means of 25 meteorobserving stations in Spain. One important goal of ournetwork is the study of the physico-chemical propertiesof meteoroids from multiple station data. Theseinclude radiant and orbital parameters, but also chemicalinformation obtained from the emission spectraproduced during the ablation of these particles of interplanetarymatter in the atmosphere. This continuousmonitoring can provide useful data to improve ourknowledge about meteoroid streams and meteoroids ofsporadic origin, and the mechanisms that deliver thesematerials to the Earth. With this aim, we analyze here asporadic fireball recorded on December 28, 2011.
