NGC 557 = IC 1703. NGC 557 comes from Swift's 6th list, sent in pieces to Dreyer before it was published in AN 2798. The final published description reads: "eF, S; B * f 15 seconds and is n of it." This differs a bit from the NGC description: "eF, S, R, * 10 nf," but not in any significant way. The star is actually southeast, but the galaxy is still almost uniquely identified by that star. Swift's RA is nearly 50 seconds of time out, and I wonder if he made a 1 minute error in reading his circles -- a 10 or 12 second error is somewhat closer to his usual accuracy.
Bigourdan did not find NGC 557 when he looked for it at the NGC place, but he did run across it a few minutes later. Thinking it was a "nova," he listed it as new and it ended up in the IC2 at its actual position.― NGC Notes by Harold Corwin
