cds-question@unistra.frvariable-starsphotometryvisible-astronomyWe analyzed the light curves of 165 AGB variables, mostly Miras, in the sky area centered between M16 and M17 (l=16, b=0), using the OGLE GVS database in the IC band. Comparison with the published light curves, derived about 50 years earlier by P. Maffei using Kodak I-N photographic plates, allowed us to ifind no significant period changes in any star. Remarkably, a few stars of the sample appear to have substantially changed their average luminosity, the most striking case being KZ Ser. We provide a better identification for three stars: IX Ser, NSV 10522, and NSV 10326, all of them being Miras. We classify the light curves of 6 stars, discovered but not classified by Maffei, (GL Ser, NSV 10271, NSV 10326, NSV 10522, NSV 10677, and NSV 10772) five of them being new Miras, and confirm the R CrB nature of V391 Sct. The magnitude scale used by Maffei is compared to the modern IC one.2022OEJV..230....1Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/OEJV/230CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/OEJV/230https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/OEJV/230http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/OEJV/230https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/OEJV/230https://vizier.iucaa.in/viz-bin/votable?-source=J/other/OEJV/230http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/OEJV/230GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/OEJV/230/table1 (Light curve parameters from OGLE data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/OEJV/230/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/OEJV/230/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/OEJV/230/table1?GETtext/xml+votable180.050000true272.0080464-14.73753670.005555555555555556Cone search capability for table J/other/OEJV/230/table2 (Stars with discrepant periods)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/OEJV/230/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/OEJV/230/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/OEJV/230/table2?GETtext/xml+votable180.050000true276.8152064-15.82651830.005555555555555556Cone search capability for table J/other/OEJV/230/table3 (OGLE data for Maffei's unclassified stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/OEJV/230/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/other/OEJV/230/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/OEJV/230/table3?GETtext/xml+votable180.050000true272.1432917-15.12741670.005555555555555556Cone search capability for table J/other/OEJV/230/table4 (Stars with possible change of the average magnitude)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/OEJV/230/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/other/OEJV/230/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/OEJV/230/table4?GETtext/xml+votable180.050000true275.0017072-13.16174250.0055555555555555565/7290 7364-7365 6/29106-29107 29110-29113 29115-29118 29154-29155 29465 29468-29469 29505-29507 29512-295132.367228618189496e-19 2.6706780932288093e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/OEJV/230?format=asciiOpticaldefaultJ/other/OEJV/230/table1Light curve parameters from OGLE datarecnoRecord number assigned by the VizieR team.
