AB Asteroid (3200) Phaeton is the par-ent body of the Geminid meteoroid stream. These par-ticles give rise to one of the strongest annual meteorshowers, with an activity period that extends fromNov. 27 to Dec. 28, peaking on Dec. 14 [1]. Ceplechaand McCrosky concluded that the bulk density ofGeminid meteoroids is of about 3–4 g/cm3[2]. How-ever, Babadzhanov obtained a value of 2.9 g/cm3[3].It is possible that the high density of Geminid meteor-oids in comparison with other meteoroids is due to thesmall perihelion distance of the Geminid orbit(q=0.141). This, in fact, would cause a depletion in themost volatile elements. One common technique to ana-lyze the composition of Geminid meteoroids is meteorspectroscopy. Thus, the SPanish Meteor Network em-ploys an array of CCD video spectrographs to deter-mine the chemical nature of meteoroids ablating in theatmosphere. In this work wepresent the analysis of abright Geminid bolide (absolute magnitude -10) ob-served over the south and center of Spain in 2012. Itsspectrum was recorded from three of our meteor ob-serving stations.
