Abstract: The main astrophysical properties of 11 previously unstudied open starclusters are probed with JHK Near-IR 2MASS photometry of Cutri et al. Cutri,R., et al., 2003. The IRSA 2MASS All-sky Point Source Catalog, NASA-IPACInfrared Science Archive and proper motions NOMAD astrometry of Zacharias etal. Zacharias, N., Monet, D., Levine, S., Urban, S., Gaume, R., Wycoff, G.,2004. American Astro. Soc. Meeting 36, 1418. The fundamental parameters havebeen derived for IC 1434, 2156; King 17, 18, 20, 23, 26}; and Dias 2, 3,4, 7, 8}, for which no prior parameters are available in the literature. Theclusters- centers coordinates and angular diameters are re-determined, whileages, distances, and color excesses for these clusters are estimated here forthe first time.
