abstract = {We analyze the likely link between the recently discovered Near Earth Object
2012XJ112 and a bright fireball observed over the south of Spain on December 27,
2012. The bolide, with an absolute magnitude of -9±1, was simultaneously imaged
during the morning twilight from two meteor stations operated by the SPanish Meteor
Network (SPMN). It was also observed by several casual witnesses. The emission
spectrum produced during the ablation of the meteoroid in the atmosphere was also
recorded. From its analysis the chemical nature of this particle was inferred. Although
our orbital association software identified several potential parent bodies for this
meteoroid, the analysis of the evolution of the orbital elements performed with the Mercury 6 symplectic integrator supports the idea that NEO 2012XJ112 is the source of
this meteoroid. The implications of this potential association are discussed here. In
particular, the meteoroid bulk chemistry is consistent with a basaltic achondrite, and this
emphasizes the importance to deduce from future Earth approaches the reflectance
spectrum and taxonomic nature of 2012XJ112.},
