IC 2509 is probably the faint star I've listed in the table. Though I overlooked this years ago when I first went over this field, I now have Bigourdan's observations at hand. His place (-11 seconds, -30 arcsec from an unnamed star of magnitude 11.5) is an estimate on a single night.

Like many other of his faint "novae", he describes is simply as a "Trace of extremely faint nebulosity, pretty surely existing; it needs a more powerful telescope."

This may be the same star that Carlson lists in her 1940 paper. But with no position listed there, we don't know for sure.
