Albert Marth discovered NGC 3863 = m 224 on 25 Mar 1865 and noted "vF, perhaps 2' l, mE, almost ray, pos 70°, glbM." His position is less than 1' south of UGC 6722 and the description matches.

400/500mm - 17.5" (1/23/88): fairly faint, thin edge-on WSW-ENE, moderately large, bright core. This pretty galaxy is located 15' N of XI Virginis (V = 4.9) within the UGC 6730 group.
