William Herschel discovered NGC 2340 = H II-736 = h433 on 9 Mar 1788 (sweep 815) and called "pF, vS, lbM, resolvable." His position (CH's reduction) is just off the east edge of the galaxy. Harold Corwin concludes that H II-862 (found on sweep 990, 28 Dec 1890), although equated with NGC 2332 = h430, is actually a duplicate observation of this galaxy. John Herschel described it on 7 Mar 1831 (sweep 329) as "pB; pL; R; gbM; 25"; two small stars preceding." and measured a more accurate position.

400/500mm - 17.5" (1/20/90): fairly faint, fairly small, elongated E-W, bright core. Brightest of four in the field with IC 458, IC 464 and IC 465 = NGC 2334? Two mag 12 stars lie 1.7' NW and 2.4' WNW of center.

600/800mm - 24" (2/13/18): at 200x and 375x; fairly bright, fairly large, oval 2:1 WSW-ENE, contains a large bright core that is weakly concentrated to the center. A couple of 12th magnitude stars are off the northwest side. Brightest in a group of mostly IC galaxies with IC 464 2.4' SSW and IC 463 3.7' SSW. Also in this string are IC 461 7' SSW and IC 465 5.7' NE!
