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