William Herschel discovered NGC 3715 = H II-562 = h3347 on 27 Mar 1786 (sweep 548) and recorded "F, S, bM, iF." There is nothing at his position, but 35 sec of RA west and 2' north is MCG -02-29-041 = PGC 35540. JH made two observations from the Cape of Good Hope and measured an accurate position.

400/500mm - 17.5" (5/2/92): fairly faint, fairly small, round, 40" diameter, even concentration, bright core, smoothly increases to core. A mag 10.5 star is 5.0' NNW of center.
