William Herschel discovered NGC 5677 = H III-283 = h1840 on 17 Feb 1785 (sweep 373) and recorded "vF, vS, about 8' south of a small triangle of pretty large stars, and just following a larger triangle of stars; a little larger than those of the former triangle." John Herschel made the single observation "F; R; r; has 3 stars 9-10m north-preceding." He made a misprint in the Slough Catalogue, equating h1840 with H. III-289, instead of H. III-283. Two additional observations were made at Birr Castle.

400/500mm - 17.5" (6/24/95): located in a field with three mag 9 stars including SAO 83402 7' NW, SAO 83404 5' WNW and a mag 9.5 star 2.0' NW of center. Fairly faint, 1.2' diameter, even surface brightness. Irregularly round, although cannot determine PA. Forms a pair with UGC 9340 8' N.
