PGC 18948
A 13th-magnitude lenticular galaxy (type (R1)SB(r)0/a) in
Canis Major (RA 06 23 46.4, Dec -32 13 00)

Based on a recessional velocity of 6725 km/sec, PGC 18948 is about 310 million light years away. Given that and its apparent size of 1.5 by 1.4 arcmin, it is about 135 thousand light years across. Used by the de Vaucouleurs Atlas of Galaxy Types (as ESO 426-2) as an example of type (R1)SB(r)0/a. (Note: the image in the de Vaucouleurs Atlas does not have North at the top.)
