Abstract
We report results on the spectroscopic follow-up of Nova SMC 2001 and Nova LMC 2002 carried out at La Silla. The analysis of the spectroscopic evolution shows that these objects belong to the {\sl Fe II} class, according to the Cerro Tololo scheme. From the line fluxes and the expansion velocities, we have derived an approximate mass for the ejected shells of 2$\div3\times 10^{-4} M_\odot$. The filling factor measurements ($ε\sim 10^{-4}÷10^{-1}$) suggest a clumpy structure for the ejecta.
