It is possible to evaluate the absolute magnitude of the Nova Delphini 2013 with visual observations submitted to AAVSO, following the works of Leonida Rosino at Asiago Observatory on the novae of M31. A naif interpretative model of the light curve is presented, based on the decreasing exponential law, in order to open to amateur astronomers a glimpse on the complex theoretical framework of these phenomena.
