Corwin's Notes
=====
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, just as he must have done with NGC 6491 and
NGC 6493.
