We are conducting a large programme to classify newly discovered Milky Way star cluster candidates from Froebrich et al. Here we present near-infrared follow-up observations of FSR 0190 (, J2000). The cluster is situated close to the Galactic plane . It shows a circular shape, and a relatively large number of core helium burning stars – which clearly distinguishes the cluster from the rich field – but no centrally condensed star density profile. We derive an age of more than 7 Gyr, a Galactocentric distance of 10.5 kpc, a distance of 10 kpc from the Sun, and an extinction ofAK= 0.8 mag. The estimated mass is at least of the order of 105M⊙, and the absolute brightness isMV≤−4.7 mag; both are rather typical properties for Palomar-type globular clusters.
