Spectra of Nova Scuti 2005 N.2 (V477 Sct)

The nova was probably entering a dust condensation episode or brightness oscillations during the transition phase when it became unobservable for the seasonal conjunction with the Sun. Absolute spectrophotometry shows it to belong to the He/N class.

The emission line width at half intensity is 2600km/s. At least five ripples are identified in the high resolution emission lines profiles at radial velocities ranging from -980 to +700km/s. The nova erupted at a large distance from the Sun and at an appreciable height above the Galactic plane, suggesting an association with the Galactic bulge (unusual for a He/N nova).
