Lewis Swift discovered IC 1228 = Sw. X-39 on 13 Sep 1890 and recorded ""vF; pS * nr n[orth]; 4 st. in curve s[outh]." His position and description matches UGC 10524.

600/800mm - 24" (6/21/17): at 375x; fairly faint or moderately bright, very elongated 3:1 NW-SE, ~45"x15". This description applies to the bright central bar of this spiral. Sometimes I could glimpse the root of the spiral arms as curved ends of the bar, particularly at the northwest end. A mag 12.7 star is 1.1' NNW of center.
