Interestingly Courtney Seligman gives the following info

GC 11388 = A magnitude 16.5 elliptical galaxy (type E1?) at RA 03 00 55.9, Dec +44 20 47
PGC 11389 = A magnitude 16.3 elliptical galaxy (type E1 pec?) at RA 03 00 55.9, Dec +44 21 01
PGC 11390 = A magnitude 15.6 elliptical galaxy (type E0?) at RA 03 00 58.6, Dec +44 20 59
Historical Identification: Per Dreyer, IC 275 (Swift list VIII (#9), 1860 RA 02 51 40, NPD 46 12.8) is "most extremely faint, pretty small, round, between 2 stars". Swift's Catalogue No. 8 note adds "Faint star near to west, double star near to southwest, following of 2", the other being IC 274. The position precesses to RA 03 00 56.2, Dec +44 20 48, on the southern side of the brightest of the three galaxies listed above, and the stars to the south and southwest make the identification certain. The main question about the identification has to do with the statement "between 2 stars", which does not seem to apply to the group unless Swift thought the eastern member of the triplet was a faint star. For that reason some think that only the western pair (PGC 11388 and 11389) should be IC 275, but it is general practice to apply the term to all three galaxies, as I have done here.
Physical Information: Based on a recessional velocity of 9735 km/sec, PGC 11389 is about 450 million light years across. Given that and its apparent size of 1.1 by 1.0 arcmin, it is about 140 thousand light years across. Presuming the other galaxies are at the same distance (LEDA lists the same recessional velocity for PGC 11388 and 11389, but NED only assigns the recessional velocity to PGC 11389), PGC 11388's apparent size of 0.45 by 0.4 arcmin corresponds to about 60 thousand light years, and PGC 11390's apparent size of 0.45 by 0.45 arcmin corresponds to about 60 thousand light years.
