Guillaume Bigourdan discovered NGC 3828 = Big 46 on 28 Mar 1886. His position matches CGCG 097-075, though CGCG (and the UGC notes to UGC 6686) fail to label this galaxy as NGC 3828. MCG labels it correctly. Mentioned by Malcolm Thomson in his "CGCG Corrections" and in Harld Corwin's identification notes.

400/500mm - 17.5" (3/29/89): very faint, very small, round. A mag 11 star is 1.7' SE. Forms a pair with edge-on UGC 6686 5.9' E. UGC 6686 appeared very faint, very small (only the central region was seen).
