Abstract

We present a list of 130 Galactic Open Clusters, found in the All-Sky Compiled Catalogue of 2.5 Million Stars (ASCC-2.5). For these clusters we determined and publish a homogeneous set of astrophysical parameters such as size, membership, motion, distance and age. In a previous work 520 already known open clusters out of the sample of 1700 clusters from the literature were confirmed in the ASCC-2.5 using independent, objective methods. Using these methods the whole sky was systematically screened for the search of new clusters. The newly detected clusters show the same distribution over the sky as the known ones. It is found, that without the {\em a-priori} knowledge about existing clusters our search lead to clusters which are, {\em on average}, brighter, have more members and cover larger angular radii than the 520 previously known ones.

Fig.2 and Fig.3 available as 1013_ASCC_13.jpg and ncomp.jpg, respectively. In fact, during this search of new clusters in the catalogue ASCC-2.5, we discovered 130 clusters. It turned out that 21 of them are listed in the online list DLAM as private communications. We stress the point that this paper is the first presentation of these 21 clusters in a refereed publication. Accepted for publication in A&A
