William Herschel discovered NGC 4146 = H III-327 on 6 Apr 1785 (sweep 393) and noted "vF, pS." CH's reduction is 13 sec of time preceding UGC 7163. There were no observations made by JH or at Birr Castle.

400/500mm - 17.5" (5/4/02): fairly faint, fairly small, round, 0.8' diameter. Weak concentration in halo but direct vision revealed a very small brighter core of ~10" (this is a Seyfert galaxy). Located 22' ESE of mag 7.1 SAO 82152.
