History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 6625. JH's RA is marked uncertain in his 1833 PT catalogue where he describes it only as "A loose straggling cluster of stars 11.. 12 m." There is no immediately obvious cluster at his position, but about two arcmin northwest there is a clump of stars, four arcmin by two arcmin in size, that might be his object. This is on the southeastern edge of a much larger clump (roughly 10 arcmin by 8 arcmin) that could also be JH's object. Neither is particularly striking, but the former has been identified as a real cluster. Since it stands out a bit more, and might make an impression during a sweep, I've adopted it as N6625.

Historical observations

John Herschel

In his G.C., Herschel describes this object as "Cluster, little compression, little richness, consists of stars of 11..12 magnitude." Herschel only observed the cluster once, and noted that there is "very considerable doubt, extending, perhaps, to a whole minute" in the RA position.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NO CL DC.
