II型超新星
The cluster is metal-rich with an iron abundance of [Fe/H] = . Despite its youth, it shows an enhancement of Alpha process elements. Possibly this is due to an enhancement of its birth molecular cloud by a nearby Type II supernova explosion. At least nine variable star members have been identified with high probability, plus 29 lower probability members. The former include two eclipsing binary star systems. The cluster is located from the galactic center, close to the galactic plane, and is not far from its birthplace.
