NGC 5650 = NGC 5652. Swift's description and position match NGC 5652, found a century earlier by William Herschel. Also observed by JH, the NGC position is pretty good -- as is Swift's. The mystery here is why neither Swift nor Dreyer caught the match. The RA's are only 8 seconds of time different, and the declinations even closer at 0.5 arcmin.
Well, there are many other matching objects with even closer coordinates that Dreyer did not catch, either. Perhaps he was giving the benefit of doubt to the observers.
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads =5652 S.
