NGC 3949 is an unbarred spiral galaxy in the constellation Ursa Major,[1] approximately 50 million light-years away from the Earth. It was discovered by German-British astronomer William Herschel on 5 February 1788.[3]
NGC 3949 is a member of the M109 Group, a group of galaxies located in the constellation Ursa Major that may contain over 50 galaxies. The brightest galaxy in the group is the spiral galaxy M109.[4][5][6]
One supernova has been observed in NGC 3949: SN 2000db (Type II, mag. 14.3) was discovered by Masakatsu Aoki on 6 August 2000.[7][8]
