Abstract : The two sources listed as 3C 343 and 3C 343.1 in the Revised 3C Catalog have very similar intensities and spectra. Since these similarities are so great, it is probable that these sources are physically connected. If so, they have by far the largest ratio of separation to component diameter for any known radio source. There is no satisfactory optical identification, although a moderately-bright galaxy lies within the small est circle which can circumscribe the source. (Author)
