SAI 28 is a sparse, moderately dense object of intermediate C3 quality. Its parallax locates it at a moderate distance, above the mid-plane. No fundamental parameter values are available for this object. It is rarely studied in the literature, with no articles listed in the last 16 years.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
