In 2005, 109 new open clusters were discovered.
109 new Galactic open clusters (Kharchenko+, 2005)

Kharchenko+ presents 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 they determined a homogeneous set of astrophysical parameters such as size, membership, motion, distance and age.
Also accurate diameters and distances were determined for 520 known open clusters.
Many "open clusters" did not qualify as open clusters using the new criteria.

The catalogue is a result of studies of wide neighborhoods of 513 open clusters and 7 compact associations carried out in the high precision homogeneous all sky catalogue ASCC-2.5 (Kharchenko, 2001, Cat.
I/280). On the basis of data on about 33000 possible members (including about 10000 most probable ones) and homogeneous methods of cluster parameter determination the angular sizes of cluster cores and coronae, cluster heliocentric distances, mean proper motions, mean radial velocities and ages were established and collected in the COCD.This was done by systematically searching a catalogue of 2.5 million stars.

The All-Sky Compiled Catalogue of 2501304 stars (ASCC-2.5) with the limiting magnitude V=12-14 is a result of a merging of star lists from
present day large high-precision catalogues
