Let's resume this discussion. We both agree on most (all-?)
issues. The 'nova' terminology is used for various astrophysical
phenomena. These systems can be divided into a few subclasses
according to their observational behaviour and / or their
different configuration.

In this case, it should be classified as a recurrent nova to be
included in the long list of all novae, but not in the classical
novae list. O.k.?
