In order to investigate the luminosity and expansion evolution of nova shells, we have started a project to reobserve the novae collected in the Downes et al. (2001) catalogue on shell luminosities. In the present article, we discuss potential problems of the Downes et al. work and conduct a first, very preliminary, analysis of the expansion evolution of our first set of shell data.
