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.
