  The Light Curve of S Andromedae
  Historical observations of S And, in combination with the color versus rate-of-decline relationship for well-observed SN 1991bg-like supernovae, are used to estimate a rate of decline Delta m15 (B) = 2.21 and an intrinsic color at maximum [B(0) - V(0)]o = 1.32 for SN 1885A.
  ---either 1885A was not a SN 1991bg-like object or that subclass has more dispersion than it is thought or the old data is bloody rotten.
