2MASX J00534840-1351148

2MASX J00534 is the northernmost galaxy in Arp 251. It spans 30 arc-seconds in apparent view, which corresponds to a diameter of 170,000 light years.  The upper arm is disturbed, meaning that galaxy interaction may be present.  

2MASX J00534765-1351358

2MASX J005347 is the southernmost galaxy out of the triplet and has a magnitude of 15.1. It's visual magnitude is unknown.

2MASX J00533671-1349541

2MASX J005446 has a magnitude of 16.4 and a redshift distance of 700 million+ light-years. It has a larger angular size than the other galaxies making up Arp 251.
