IC 4196
IC 4196
History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
IC 4196 = NGC 4970. Swift found this and two other nebulae (I4180 and I4197) in the area on 27 February 1898. My guess is that he simply forgot to check the NGC, or else he did check and missed NGC 4970. WH's position is very close to the modern positions, and Swift's is within two arcmin of WH's.
However, Dreyer also missed the identity, as did Howe when he went over the field, presumably in 1899 (his note in MNRAS 61, 31, 1900 where he also corrects the position for IC 4197, Swift's "3rd of 3").
The galaxy is positively identified by Swift's note "11m * near p". Dreyer adopted Howe's distance (4 arcmin) to the star for the IC description.
