UBC 63 is probably not one cluster but two—a 21-Myr-old and a 562-Myr-old system—that had a close, unbound flyby about 6 Myr ago and are now separating.

abstract
We present structural parameters for 51 compact star clusters from the survey of star clusters conducted in the South-West field of the M31 disk by Kodaira et al. (2004). Structural parameters of the clusters were derived by fitting the 2-D King and EFF (Elson, Fall and Freeman 1987) models to the V-band cluster images. Structural parameters derived for two M31 clusters, which are in common with the study based on the HST data (Barmby et al. 2002), are consistent with earlier determination. The M31 star cluster structural parameters in general are compatible with the corresponding Milky Way galaxy and Magellanic Clouds cluster parameters.

Discovery of an Unbound Flyby Companion of UBC 63: In the Immediate Aftermath of a Close Encounter
UBC 63 is probably not one cluster but two—a 21-Myr-old and a 562-Myr-old system—that had a close, unbound flyby about 6 Myr ago and are now separating.
