Arp 299 (also known as IC 694 and NGC 3690) is a pair of colliding galaxies approximately 134 million light-years away in the constellation Ursa Major. Both of the galaxies involved in the collision are barred irregular galaxies. The interaction of the two galaxies in Arp 299 produced young powerful starburst regions. Six supernovae have been detected in Arp 299: SN 1992bu, SN 1993G, SN 1998T, SN 1999D were observed in NGC 3690 while SN 1990al and SN 2005U were observed in IC 694.
