We have detected an absorption feature at 6695.6 Å that we have identified as blueshifted <SUP>7</SUP>Li i λ6708 Å. The absorption line, moving at -550 km s<SUP>-1</SUP>, was observed in five high-resolution spectra of the nova obtained at different epochs. Based on the intensity of this absorption line, we infer that a single nova outburst can inject in the Galaxy {M}<SUB>{Li</SUB>} = 0.3-4.8 × 10<SUP>-10</SUP> {M}<SUB>☉ </SUB>. Given the current estimates of the Galactic nova rate, this amount is sufficient to explain the puzzling origin of the overabundance of lithium observed in young star populations.STAMPAenArticle10.1088/2041-8205/808/1/L142-s2.0-84958162827000358778900014https://iopscience.iop.org/article/10.1088/2041-8205/808/1/L142015ApJ...808L..14IFIS/05 - ASTRONOMIA E ASTROFISICA
