NGC 3524 is a lenticular galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 1709 ± 25 km/s, which corresponds to a Hubble distance of 25.21 ± 1.80 Mpc (~82.2 million light-years).[1] It was discovered by German-British astronomer William Herschel on 11 March 1784.[2]

One supernova has been observed in NGC 3524: SN 2024inv (Type Ia, mag. 18.3072) was discovered by Automatic Learning for the Rapid Classification of Events (ALeRCE) on 10 May 2024.[3] This supernova got as bright as magnitude 12.1, making it the second-brightest observed in the year 2024.[4][5]
