Observation history
NGC 5641 was discovered by Édouard Stephan on 4 June 1880. John Louis Emil Dreyer inside the New General Catalogue, described the galaxy as "pretty bright, pretty small, a little extended, much brighter middle, mottled but not resolved?" It was described in Burnham's Celestial Handbook as "pretty bright, pretty small, slightly elongated and much brighter in the middle". Walter Scott Houston also noted that this galaxy was missed by William Herschel. He wrote "although NGC 5641 is only 2' long, this should not have been a problem for Herschel observing at 157x."
