Here, we present a collection of 18443 rotating variables located toward the Galactic bulge, identified in the photometric database of the Optical Gravitational Lensing Experiment (OGLE) project. These stars exhibit distinct magnetic activity, including starspots and flares. With this collection, we provide long-term, time-series photometry in Cousins I- and Johnson V-band obtained by OGLE since 1997, and basic observational parameters, i.e., equatorial coordinates, rotation periods, mean brightness, and brightness amplitudes in both bands. This is a unique dataset for studying stellar magnetic activity, including activity cycles.</description><source format="bibcode">2024AcA....74....1I</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/74/1</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/74/1</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/74/1</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/74/1</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/74/1</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/74/1</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/74/1</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/AcA/74/1/ident (Identification of stars)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/74/1/ident?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/74/1/ident?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/74/1/ident?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>258.2235</ra><dec>-29.6900556</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>4/1794-1795 1798 1803 1805 5/7174-7175 7198 7200-7201 7204-7205 7209-7211 7216-7217 7219 7224 7226-7227 7230 7243 7296 7301 7312-7313 7316 7318 10591 12010 6/28683 28686-28687 28744 28746-28747 28750-28751 28756-28757 28784 28786-28787 28796 28798-28799 28808 28810-28811 28814-28815 28825-28829 28831-28833 28835 28872-28873 28875 28902-28903 28912 28914-28916 28924 28926 28928 28966 29056 29058-29059 29064-29066 29188 29190 29201 29203 29256-29257 29259-29261 29268 29270 42357 42359 42452-42453 42461 42495 42837 47869 47871 48033-48036 48038-48039</spatial><spectral>2.367228618189496e-19 3.852589004194616e-19</spectral><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/74/1?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>J/AcA/74/1/ident</name><description>Identification of stars</description><column><name>recno</name><description>Record number assigned by the VizieR team.
