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

NGC 5565 -- is this a star? Swift claims this is just 30 arcsec south of NGC 5564, but there is nothing there. Just a bit further on to the southeast, though, is a star at V = 15.5. Swift could just possibly have seen this, and he may have thought it a third nebula since there are two others near (see NGC 5558).

However, he claims to have found all three objects on the same night. So, I find it curious that he describes the star field around the other two carefully, and mentions in their descriptions "np of 2" and "sf of 2" with only a casual reference to this object "two others nr" in his description of NGC 5558 = NGC 5552.

This leaves open the possibility that N5565 is the same as N5563, about a minute of time following. The declinations of N5565 and N5563, however, are four arcmin different, while the declinations of the other two nebulae that Swift found on this night are very good.

The most likely hypothesis remains that Swift saw a star, but we cannot now be sure.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF S.
