Object name: ARP280
Designation(s): ARP280, NGC3769, PGC36008,
Arp 280/NGC 3769 is a pair of probably interacting galaxies in Ursa Major at a distance of 50 million light-years most say. Redshift puts it a bit closer at 44. It is a member of the Ursa Major Cloud of galaxies which are thought to range about 50 to 55 million light-years distant and includes M108 and M109 as its most famous members. Arp put it in his class of interacting double galaxies. It was discovered by William Herschel on February 5, 1788. It isn't in either Herschel 400 program though is within easy reach of an 8" telescope from dark skies at a visual magnitude of 11.7.
