Interstellar reddening and distance of Nova Cygni 1978.

- Abstract
THE interstellar feature of KI (λ7699 Å) has been observed in the direction of Nova Cygni 1978 with an equivalent width of Wλ≃116 mÅ and has been used here to deduce a colour excess of E(B−V) = 0.38 ± 0.08 mag. The distance-reddening law to the nova is derived from a sample of stars in the nearby field surrounding the nova. The nova seems to be at a distance of r≃3.3±0.6 kpc with a corresponding absolute visual magnitude at maximum light of MVo≃−7.5±0.5 mag. Nova Cygni 1978 is classified as a fast galactic nova on the basis of its absolute magnitude at maximum light and the rate of decline towards minimum light.
