William Herschel discovered NGC 3876 = H III-103 on 15 Apr 1784 (sweep 194) and noted "vF, r." His position is 4' northeast of UGC 6730 and 4.5' north-northeast of UGC 6734, a much fainter galaxy. Rudolph Spitaler measured an accurate micrometric position on 24 Mar 1892 using the 27" refractor at Vienna (given in the IC 1 notes).

The major catalogues UGC, CGCG and MCG do not label UGC 6730 as NGC 3876, but it is identified correctly in the RNGC.

400/500mm - 17.5" (1/23/88): fairly faint, fairly small, slightly elongated, brighter core. A mag 13.5 star is 1.2' NE. Located 5.7' E of mag 8.6 SAO 119025.
