History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 6497 = NGC 6498. Swift found his 80th and 81st nebulae on 16 Sept and 26 Sept 1884, respectively. The positions are only 1 second of time and 32 arcsec apart, and the descriptions are close enough that the only galaxy in the area can match both. In particular, Swift says of N6497, "Close s of middle * of 3 in a line, middle * the fainter;" and of N6498, "B * nr; F * v nr." The middle star in the line is the "faint star very near," and the bright star is the eastern of the three stars.

So, I'm almost certain that the two observations refer to the same object, and that Swift added the comments "np of 2" and "sf of 2" as he was preparing his first list for publication.
