Spectroscopy of a globular cluster in the Local Group dwarf irregular NGC 6822

We present low-resolution Keck spectroscopy for the globular cluster (GC) H VIII in the Local Group dwarf irregular galaxy NGC 6822. We find the metallicity of the cluster to be [Fe/H]=−1.58 ± 0.28 and the age of the cluster to be 3–4 Gyr, slightly older than but consistent with previous age estimates. H VIII seems to be more metal-poor than most intermediate-age GCs in the Local Group, and appears most similar to the anomalous Small Magellanic Cloud clusters Lindsay 113 and NGC 339.
