These observations, together with published radio data and Midcourse Space Experiment and Spitzer images, were used to determine some of the physical parameters of the region. We found 96 cluster member candidates in an area of about 1.5x2.0arcmin2, 30% of them showing excess emission in the near-IR. Description: The NIR imaging photometric observations were performed in 2003 May in the direction of IRAS point source 17149-3916, using the NIR camera of the Laboratorio Nacional de Astrofisica, Brazil, mounted on the 0.6m Boller & Chivens (BC) telescope; the resulting plate scale of the images is 0.48/pix.
