Open cluster survey within 1 kpc by the Gaia DR2

We conducted a survey of open clusters within 1 kpc from the Sun using the astrometric and photometric data of Gaia DR2. We found 664 cluster candidates by visual inspection of the stellar distributions in proper motion space and spatial distributions in l-b space. All of the 664 cluster candidates have a well defined main-sequence except for two candidates if we consider that the main sequence of very young clusters are somewhat broad due to differential extinctions. Cross-matching of 662 open clusters with known open clusters in various catalogs resulted in 209 new open clusters. We present the basic data of newly discovered open clusters along with a brief description of the property of the new clusters. The majority of newly discovered open clusters have young and intermediate ages and they are likely to have member stars less than ~50.
