![]() There are several fainter nebulae closer to Swift's position than PGC 55687, but none of them fits Swift's description of the field, so the object is almost certainly the galaxy listed above or (as noted first) lost or nonexistent. However, per Corwin, Swift's original note includes 'near one of 6 or 8 stars in a curve', and on that basis he suggests that what Swift observed was U9945 (= PGC 55687). The position precesses to RA 15 34 58.4, Dec +04 41 58 (whence the position above), but there is nothing there, and almost all modern catalogs list the object as nonexistent. ![]() Historical Identification: Per Dreyer, IC 4552 (= Swift list XI (#181), 1860 RA 15 28 01, NPD 84 49.8) is 'extremely faint, pretty small, round'.
