William Herschel discovered NGC 3713 = H II-367 = h906 on 11 Apr 1785 (sweep 396) and noted "F, vS." JH made three observations and his mean position matches UGC 6511. NGC 3927, from d'Arrest, is probably a duplicate observation with a 20 minute error in RA. See that number.

400/500mm - 17.5" (4/9/99): fairly faint, small, slightly elongated NW-SE, 0.8'x0.6', bright core increases to a quasi-stellar nucleus, halo is ill-defined. Brightest of 4 in region with NGC 3714 13' NNE, UGC 6522 11' SE and CGCG 156-92 5.5' NW.
