IC 1921 may be the faint star that I've listed in the position table. However, the star is fainter than I'd expect Stewart to be able to pick up on the Bruce plates, so I suspect that the object that he found is actually a plate defect. His description is simply "Stell[ar]", so doesn't help us much.

Only an examination of the original plate will tell us for sure. See IC 1923 for more on this particular plate.

Courtney Seligman has just (July 2021) written that this object has been linked with the star CD -47 1297 on several internet sites. This just can't be correct as the star is at 04 11 43.02, -47 16 16.1 (J2000), while Stewart's position -- correctly copied into IC2 -- is 03 24 42, -50 41.9 (also J2000). The separation is 8.4 degrees, not exactly good -- or even "good enough" -- agreement. While we don't yet know the source of this error, Courtney is pretty confident in his assertion that IC 1921 can't be CD -47 1297. I agree!
