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).^[1] In addition, 11 non redshift measurements give a distance of 17.582 ± 1.088 Mpc (~57.3 million light-years).^[2] The galaxy was discovered by German-British astronomer William Herschel on 8 April 1793.^[3]

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.^[4]

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 [d], and UGCA 211 [d].^[5]

Supernova

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.^[6] Later analysis suggested that the supernova was Type IIn-L with a red supergiant progenitor.^[7]
