William Herschel discovered NGC 6073 = H III-74 = h1948 on 21 Mar 1784 (sweep 183) and noted "vF, S, r. Pointed out by 157 and verified at 240." Caroline's reduced position is 2' north-northeast of UGC 10235. It was looked for once at Birr Castle, but not found.

400/500mm - 17.5" faint, fairly small, oval NW-SE, broad weak concentration and has a fairly even surface brightness overall.
