IC 2484 is lost. Swift calls this "pB, S, R; 7 m * nf, D * p". The description is identical in the three different journals where it was published. It was the only nebula he found the night of 22 Jan 1898.

During my SGC work, I noted that this may be a triple star. Now (Dec 2002), however, I cannot find a triple near the nominal place that might have caught my eye twenty years ago.

I've also searched the southern sky survey films near the obvious places where the object might be: 10 minutes east and west, an hour east and west, and north along Swift's nominal RA. Since this is one of the southern-most of the nebulae that Swift claims to have seen, I've only checked southwards on the sky survey plate carrying the nominal position.

Perhaps there is a double error in his position: 10 minutes in RA and 10 degrees in Dec, for example. I'll leave these possibilities for others to explore.
