William Herschel discovered NGC 2678 = H VIII-10 = h528 on 15 Mar 1784 (sweep 172), noting a "a cluster of very coarse scattered stars, not rich." John Herschel made four observations and reported on 23 Mar 1830 (sweep 242), "A poor cluster of 4 or 5 large and a few scattered small stars." Both of the Herschel's positions point to 4 or 5 mag 9/10 stars with a few fainter stars -- an unimpressive asterism. RNGC classifies the number as nonexistent.

400/500mm - 18" (3/5/05): this asterism contains two groupings of stars to the south of M67 which is partly in the field of the 31 Nagler at the north side. The northern subgroup contains two mag 8.8 and 9.3 stars separated by 3' with a fainter double star between. About 9' SW is a nice group of 5 stars surrounding mag 8.4 HD 75373. Several mag 10-11 stars are to the SW including a NW-SE string.
