NGC 6308 is a large intermediate spiral galaxy in the constellation of Hercules. Its velocity with respect to the cosmic microwave background is 8797 ± 3 km/s, which corresponds to a Hubble distance of 129.74 ± 9.08 Mpc (~423 million light-years).[1] It was discovered by German astronomer Albert Marth on 6 June 1863.[2]
NGC 6308 has been identified as field galaxy, i.e. it does not belong to a cluster or group.[3]
One supernova has been observed in NGC 6308: SN 2023oyz (Type Ic, mag. 20.4214) was discovered by the Zwicky Transient Facility on 9 August 2023.[4]
