Three new obscured Milky Way clusters were detected as surface density peaks in the 2MASS point source catalog during our on-going search for hidden globular clusters and massive Arches-like star clusters. One more cluster was discovered serendipitously during a visual inspection of the candidates. The first deep J, H, and Ks imaging of the cluster [IBP 2002] CC 01 is presented. We estimated a cluster age of ~1–3 Myr, distance modulus of mag ( kpc), and extinction of mag. We also derived the initial mass function slope for the cluster: ). The integration over the initial mass function yielded a total cluster mass . CC 01 appears to be a regular, not very massive star cluster, whose formation has probably been induced by the shock front from the nearby Hii region Sh 2-228.
