However, one non-redshift measurement gives a much closer distance of . It was discovered by German astronomer Heinrich d'Arrest on 9 May 1864.
NGC 4615 is listed in Halton Arp's Atlas of Peculiar Galaxies as Arp34, as an example of a galaxy that looks like a stretched-out S shape.
NGC 4615 and NGC 4614 are listed together as Holm439 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937. This grouping was also listed by A. P. Mahtessian in a paper published in 1998.
