NGC 3206 is a barred spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background is 1309 ± 11 km/s, which corresponds to a Hubble distance of 19.31 ± 1.36 Mpc (∼63 million light-years). In addition, 11 non redshift measurements give a distance of 17.582 ± 1.088 Mpc (~57.3 million light-years). The galaxy was discovered by German-British astronomer William Herschel on 8 April 1793.
According to the SIMBAD database, NGC 3206 is an Active Galaxy Nucleus Candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
One supernova has been observed in NGC 3206: American amateur astronomer Patrick Wiggins discovered SN 2024bch (type II, mag. 16.1) on 29 January 2024.
NGC 3264 Group
NGC 3206 is part of the NGC 3264 group (also known as LGG 201), which includes at least five other members: NGC 3220, NGC 3264, NGC 3353, UGC 5848, and UGCA 211.
