NGC 4611 is anintermediate spiral galaxy in theconstellation ofComa Berenices. Its velocity with respect to thecosmic microwave background is 6,437 ± 22 km/s, which corresponds to aHubble distance of 94.9 ± 6.7 Mpc (~310 millionlight-years).[1] It was discovered by French astronomerÉdouard Stephan on 17 May 1881.[2] This galaxy was also observed by the American astronomerLewis Swift on 20 April 1889, and listed in theIndex Catalogue as IC 805.[2]
According to theSIMBAD database, NGC 4611 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.[3]
Onesupernova has been observed in NGC 4611:SN 2023dtz (Type Ia, mag. 18.1) was discovered byATLAS on 21 March 2023.[4]
