William Herschel discovered NGC 4665 = H I-142 = h1419 on 30 Apr 1786 (sweep 558) and recorded "cB, pL, iR, gmbM. His position matches UGC 7924 = PGC 42970. JH logged (first of two sweeps) "B; not vL; vsbM; has a * 10m 45° sp at 1' distance." NGC 4664 = H II-30 is a duplicate (earlier) observation, but he made a 10' error in the north polar distance. And JH's h1390 = NGC 4624 may also be another observation of this galaxy.

400/500mm - 17.5" (3/24/90): bright, moderately large, oval NNW-SSE, prominent core. A mag 15 star is at the NNW end 1.2' from center. Located 1.7' NE of a mag 10 star.
