| Description | Arp is positively fulsome in his description here: "Same as 310, but shows surrounding field and group. Picture is 4X of preceding (No. 310) area". The two larger galaxies (IC 1258 and 59) certainly do appear to be exchanging mass. The connection to IC 1260 is a little more tenuous but still suggested.
