History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
NGC 5840. Unless this is IC 4533 1 deg 43 arcmin south of Swift's nominal position, the object is probably lost. There is nothing else nearby that Swift could have seen, and he leaves us nothing to go on in the way of other clues. His description reads only "eeeF, pS, lE, ee diff[icult]."
IC 4533 is also unlikely to be the object Swift saw because there is a brighter star just a couple of arcminutes northeast of the galaxy; Swift would probably have mentioned the star in his description, as Javelle in fact did.
Published comments
Sulentic & Tifft (1973)
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF S.
