cds-question@unistra.frsurveysvariable-starsWe initiated digitization of the Moscow collection of astronomical plates using flatbed scanners. Techniques of photographic photometry of the digital images were applied, enabling an effective search for new variable stars. Our search for new variables among 140000 stars in the 10{deg}x5{deg} northern half of the field centered at 66 Oph, photographed with the Sternberg Institute's 40-cm astrograph in 1976-1995, gave 274 new discoveries, among them: 2 probable Population II Cepheids, 81 eclipsing variables, 5 high-amplitude delta Sct stars (HADSs), 82 RR Lyr stars, 62 red irregular variables and 41 red semiregular stars, 1 slow irregular variable not red in color. Ephemerides were determined for periodic variable stars. We detected about 30 variability suspects for follow-up CCD observations, confirmed 11 stars from the New Catalog of Suspected Variable Stars, and derived new ephemerides for 2 stars already contained in the General Catalog of Variable Stars.2008AcA....58..279Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/58/279CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.sai.msu.su/gcvs/digit/mdv/ : MDV Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/58/279https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/58/279http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/58/279https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/58/279https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/58/279http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/58/279GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/58/279/table1 (New Moscow Digital Variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/58/279/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/58/279/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/58/279/table1?GETtext/xml+votable180.050000true265.0326254.40777780.005555555555555556Cone search capability for table J/AcA/58/279/table2 (New data on known variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/58/279/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/58/279/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/58/279/table2?GETtext/xml+votable180.050000true265.05545836.04772220.0055555555555555564/1987 5/7941-7943 7945-7947 7960 7972 6/30398-30399 31101 31757 31759 31761-31763 31777 31779 31810 31816 31818-31819 31822 31844 31846 31848 31873 31876 31878 31892 31894https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/58/279?format=asciiOpticaldefaultJ/AcA/58/279/table1New Moscow Digital VariablesrecnoRecord number assigned by the VizieR team.
