Barbá 2: A new supergiant-rich Galactic stellar cluster

We present a new supergiant-rich stellar cluster hidden by extinction and christen it as Barbá 2, in honor of its discoverer Rodolfo Barbá. The cluster is at a distance of $7.39_{-0.55}^{+0.65}$ kpc and contains several supergiants, of which we provide spectral classifications for one blue, one yellow, and five red ones. The cluster extinction indicates an above-average grain-size ($R_{5495}\sim 3.7$), its age has a minimum value of 10 Ma, and its core radius is $0.84\pm 0.19$ pc.
