cds-question@unistra.fropen-star-clustersproper-motionsstellar-distancevisible-astronomyWe conducted a survey of open clusters within 1 kpc from the Sun using the astrometric and photometric data of the Gaia Data Release 2. We found 655 cluster candidates by visual inspection of the stellar distributions in proper motion space and spatial distributions in l-b space. All of the 655 cluster candidates have a well defined main-sequence except for two candidates if we consider that the main sequence of very young clusters is somewhat broad due to differential extinction. Cross-matching of our 653 open clusters with known open clusters in various catalogs resulted in 207 new open clusters. We present the physical properties of the newly discovered open clusters. The majority of the newly discovered open clusters are of young to intermediate age and have less than ~50 member stars.2019JKoAS..52..145Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/JKOAS/52.145CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/JKOAS/52.145https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/JKOAS/52.145http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/JKOAS/52.145https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/JKOAS/52.145https://vizier.iucaa.in/viz-bin/votable?-source=J/other/JKOAS/52.145http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/JKOAS/52.145GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/JKOAS/52.145/table2 (Physical parameters of newly discovered open clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/JKOAS/52.145/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/JKOAS/52.145/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/JKOAS/52.145/table2?GETtext/xml+votable180.050000true281.3728-23.74380.0055555555555555566/259 1428 1656 1658 1741 1772 1921 1970 1999 2374 2381 2463 3110 3163 3232 3363 3469 3481 3516 3617 3684 3699 3748 3752 3778 6827 7040 12824 12832 12891 12915 12986 12995 13014 13016 13046 13100 13162 13229 13266 13310 13746 13982 14014 14076 14094 14103 14126 14164 14259 14347 14352 14376 14391 14403 14418 14425 14510 14613 14644 14672 14676 14687 14706 14799 14857 14923 15366 15368 15389 15420 15462 15471 15485 15525 15560 15590 15642 15656 15668 15677 15681 15698 15706-15707 15712 15731 15743 15747 15764 15830 15948 20825 20844 20858 20984 21267 21328 21450 21467 21562 21568 21584 21667 22018 22034 22084 22098 22320 23027 23281 23584 23685 24096 24399 24423 24485 28976 28997 29040 29101 29108 29121 29134 29144 29156-29158 29169 29653 29690 29864-29865 29874 29900 29915 30114 30243 30247 30249 30268 30293 30359 30366 30567 30614 30626 30697 32066 32080 32095 32126 32218 32221 37147 37224 37613 37679 37725 37781 37806 37816-37817 37947 38119 38562 38975 39028 39372 39407 39527 39698 39963 40129 41141 41200 41314 41381 41387 41554-41555 41776 41788 41814 41816 41829 41944 42026 42046 42162 42165 42291 42336 42415 42503 42850 43062 43191 43218 43295 43450 47784 47828 47854 49099https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/JKOAS/52.145?format=asciiOpticaldefaultJ/other/JKOAS/52.145/table2Physical parameters of newly discovered open clustersrecnoRecord number assigned by the VizieR team.
