Type: galaxy, SBa
Mag: B=13.44, V=12.82
Size: 1.584′ x 1.412′
Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, vS, R, 10 arcseconds, the following of two. A sar 8m follows nearly on the parallel, another to the north."
This barred spiral galaxy is described in the NGC as "faint, very small, round, 8th mag star following, following of two." The preceding galaxy is NGC 7232.
De Vaucouleurs (1956) "Survey of bright galaxies south of -35° declination", Mem. Mount Stromlo, No. 13. (photographic study, plates taken with the 30-inch Reynolds reflector, 20-inch diaphragm); List II, p 68-73.
Bergwall et.al. (1978(Astron. Astrophys. Suppl. 33, 243-255) gives this galaxy's B-magnitude in the Johnson system as 13.44. Photoelectric UBV measurements give V=12.819 for a 66'' diaphragm and V=13.631 for a 22'' diaphragm.
Sandage (1975(Astrophysical Journal, 202, 563-582) notes that this galaxy is a member of the NGC 7213 Group. Members include NGC 7213, NGC 7232, NGC 7233 & IC 5181.
The RNGC (Sulentic and Tifft 1973) notes that this is a galaxy.

A 15.5-inch telescope shows this pair of galaxies in the same field, with NGC 7233 considerably dimmer than its companion. The galaxy appears as an elongated smudge of faint light. Immediately following the galaxy pair are two bright, slightly reddish stars.

NGC 7232 appears as a soft, faint and elongated thin dust lane, with a bright center. To the east two rather lovely yellow 8 magnitude stars follows on the parallel to the north round off the picture. The very faint member NGC 7232B was not visible. In comparison to NGC 7232, NGC 7233 is slightly round and fainter, just east of NGC 7232. To the east two rather lovely yellow 8 magnitude stars round off the picture. The very faint member NGC 7232B was not visible, also call ESO 289-G09?. Brian Skiff I did however manage to find what Magda calls NGC 7232B = ESO 289-G09, but it was too faint in 15cm aperture to see other than a very-low-surface- brightness smudge (total V only ~13 [rather uncertain] and mean surface brightness only muV = 14.4!).
