We carried out a 2MASS J, H and Ks survey of infrared star clusters in the
Milky Way sector 230
. This zone was the least studied in the literature,
previously including only 12 infrared clusters or stellar groups
with 
10°,
according to the recent catalogue by Bica et al. (2003).
We concentrated efforts on embedded clusters, which are
those expected in the areas of known radio and optical nebulae. The present study provides
179 new infrared clusters and stellar groups, which are interesting targets for detailed future
infrared studies. The sample of catalogued infrared clusters and stellar groups in the Galaxy is
now increased by 63%.
