Object name: ARP103
Designation(s): ARP103, NGC6241, ZWICKYS_CONNECTED_MULTIPLE_SYSTEM, ZWICKYS_TRIPLET,
Arp 103 is also known as Zwicky's Connected Multiple System or Zwicky's Triplet depending on who you read. It consists of three galaxies. They have many different designations, none all that common. NED prefers UGC 10586 Notes 3, UGC 10586 Notes 4 and UGC 10586 Noted 5. Also in the image are UGC 10586, UGC 10586 Notes 1 and UGC 10586 Notes 2. So by the UGC, it is a 6 galaxy system. UGC 10586 notes 2 is better known as NGC 6241. These galaxies are located in the constellation of Hercules at a distance of about 425 million light years. It consists of two southern galaxies, Notes 3 and 4 and a northern galaxy 2.5 minutes north. A faint arm connects Notes 3 and 5. Several knots are seen in it. About halfway between the two is another faint arm running at nearly right angles to the connecting arm which contains a broad extension on the western side. It makes the lower galaxy look much like the Umbrella Galaxy, Arp 189. I can't see it continuing beyond this point, rather the plume from the northern galaxy comes down to meet it. Thus there may be no true connection. The horizontal bar is only hinted at in Arp's image but appears rather obvious in mine. Also not seen well in Arp's image is the large splash of stars that surrounds the southern pair. The knots in the connecting arm appear somewhat blue indicating new stars.
