NGC 7431 is pinpointed by Bigourdan's micrometric observation as a double compact galaxy just three arcmin preceding NGC 7433. The NGC position, derived from Bigourdan's observation, is fortuitously within one or two arcsec of the true position. The brighter preceding object is included in GSC, and is one of the Lick Northern Proper Motion survey reference galaxies.
The RNGC (Sulentic and Tifft 1973) notes that this is a 15.5 mag galaxy. Their coded description reads SLEL,STEL.
