Discovered by Whiting, Hau and Irwin in 2002.
Identified as globular cluster by Giovanni Carraro in 2005.
During their hunt for new Local Group galaxies, Whiting, Hau and Irwin (2002) discovered this object and cataloged it as WHI B0200-03, as a suspected star cluster.
Based on CCD photometry in the BVI bands of the spectrum, Carraro (2005) identified it as a compact star cluster of low metallicity ([Fe/H]=-1.20) of approximate age of 5 billion years. It is clearly a halo object, and definitely not an open cluster, but probably one of the youngest globular clusters in the Milky Way's halo.
