Object name: ARP143
Designation(s): ARP143, NGC2444, NGC2445, CGCG206, 022,
Arp 143 is a pair of colliding galaxies in Lynx about 190 million light-years distant. The pair was discovered by Édouard Stephan on January 18, 1877. The red galaxy, NGC 2444, is classified as S0 pec while the blue one, NGC 2445 is an irregular of the Magellan type. It may have had some other structure prior to being torn apart by the much denser NGC 2444 which appears to be a "red and dead" galaxy though starburst activity is seen in its core thanks to the collision. NGC 2445 is packed with very blue star clusters in HII regions. Unfortunately, its redshift is too great for me to get any H alpha data on it as it has been moved out of my passband.
