Scientific paper

Yearly spectra obtained for an extremely slow nova in the bulge of M31 for 1986-1990 cover the nova's evolution in the nebular phase. The derived nebula gas, electron temperature, and abundances are typical of Galactic slow novae. While a previous study has found evidence of a systematic difference in a proportion of the types of observed outbursts between M31 bulge novae and Galactic novae, these results indicate that, in the case of individual novae, the general disparate properties of nova outbursts likely overwhelm relatively smaller differences. Implications for the use of extragalactic novae as distance indicators are noted.
