Observations by Hartwig, Wolf, Dunér and Bigourdan are used to show that SN 1885a reached MV(max) = −18.8 ± 0.5 on 17 or 18 August 1885. The lightcurve of S And is found to have declined more rapidly after maximum than that of any other well-observed supernova. The existence of S And and the relatively young age of the supernova remnant Sgr A East appear to indicate that the supernova frequencies near the nucleus of M31 and the Galactic centre are respectively ∽102 and ∽103 times higher than expected. It is spectulated that S And may belong to a population of supernovae (“type 0”) that only occur near the nuclei of giant galaxies. Beyond the Local Group such objects might perhaps have been missed because of their fast decline and close proximity to luminous nuclei.
