cds-question@unistra.freclipsing-binary-starsphotometryvisible-astronomyObservations of {beta} Lyr in four months of 2018 by three BRIght Target Explorer (BRITE) Constellation satellites, the red-filter BRITE-Toronto and BRITE-Heweliusz, and the blue-filter BRITE-Lem, permitted a first, limited look into the light-curve variability in two spectral bands. The variations were found to be well correlated outside the innermost phases of the primary eclipses with the blue variations appearing to have smaller amplitudes than the red; this reduction may reflect their presumed origin in the cooler, outer parts of the accretion disk. This result must be confirmed with more extensive material as the current conclusions are based on observations spanning slightly less than three orbital cycles of the binary. The assumption of an instrumental problem and the applied corrections made to explain the unexpectedly large amplitude of the red-filter light curve observed with the BRITE-Toronto satellite in 2016 are fully confirmed by the 2018 results.2019AJ....158..148Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/158/148CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/110/1350 : Beta Lyrae light curve changes (Van Hamme+ 1995)J/A+A/312/879 : Beta Lyr radial velocities and UBV data (Harmanec+, 1996)J/A+A/463/233 : UBV and radial velocity light curves of beta Lyr (Ak+, 2007)J/ApJ/750/59 : BVR polarimetric observations of {beta} Lyr (Lomax+, 2012)J/A+A/618/A112 : {beta} Lyr light curves (Mourard+, 2018)J/AJ/156/12 : Photometry of {beta} Lyrae by the BRITE satelliteshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/158/148https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/158/148http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/158/148https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/158/148https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/158/148http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/158/148GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/158/148/table1The satellite-orbit, average datarecnoRecord number assigned by the VizieR team.
