Object name: ARP028
Arp 28 sits in a rather empty part of the sky. It is in Arp's class: Spiral Galaxies: One heavy arm. In some cases, I've had trouble seeing which arm Arp was talking about but this one is quite obvious for a change. Arp 28 is also known as NGC 7678 and is located near the center of the Great Square of Pegasus. It is classed as SAB(rs)c and is both a Seyfert 2 and starburst galaxy. It appears that heavy arm as a lot to do with the starburst classification. Arp's note: "Note straight heavy arm." The heavy arm is somewhat straight but so are other arm segments of the galaxy. It certainly is a disturbed galaxy. Redshift puts it about 140 million light-years away. A single Sosies measurement shows a slightly closer distance of 115 million light years. I'm not sure such a measurement is all that accurate for a highly disturbed galaxy but then neither is redshift if the galaxy has had a close encounter that has accelerated it. The galaxy was discovered by William Herschel on September 15, 1784 but isn't in either of the Herschel 400 programs.
