Overview
HSC 2849 is a sparse, moderately dense object of very high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a metal-poor, very young cluster (see Parameters). It was recently reported in the literature.
Note: This is a unique object, which shares a very small percentage of members with at least one previously reported entry, and a very small percentage with at least one entry reported in the same catalogue. See table with shared members information.
