This one is so obvious that I got it for SEGC. The IC description reads simply "vS Cl, [NGC] 6778 p 3 [arcmin]." This is just where Bigourdan's three micrometric measurements made on two nights place his "cluster." It is probably a random grouping of 8-9 stars at Bigourdan's place -- but it certainly does look like small cluster. Once we have proper motions for the stars, we'll know better whether they might be associated.
In the meantime, I suspect this would be an interesting object in a moderate size (say 15- to 20-inch) telescope. And it is indeed just three arcmin east of NGC 6778 = NGC 6785 (which has its own story).― IC Notes by Harold Corwin
