NGC 3206 is abarred spiral galaxy in theconstellation ofUrsa Major. Its velocity with respect to thecosmic microwave background is 1309 ± 11 km/s, which corresponds to aHubble distance of 19.31 ± 1.36Mpc (~63 millionlight-years).[1] In addition, 11non redshift measurements give a distance of 17.582 ± 1.088 Mpc (~57.3 million light-years).[2] The galaxy was discovered by German-British astronomerWilliam Herschel on 8 April 1793.[3]
According to theSIMBAD database, NGC 3206 is anActive 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]
Onesupernova has been observed in NGC 3206: American amateur astronomerPatrick Wiggins discovered SN 2024bch (type II, mag. 16.1) on 29 January 2024.[5]
NGC 3206 is part of the NGC 3264group (also known asLGG 201), which includes at least five other members:NGC 3220,NGC 3264,NGC 3353, UGC 5848, and UGCA 211.[6]
