NGC 6731 is probably the double star whose position I give in the main table. It was found by J. G. Lohse, and is similar to other "nebulae" found by him (e.g. NGC 6344 and NGC 6767, both of which see). He describes it simply as "Very faint," though, so the identification is not as secure as it might be.
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF S.
