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.
