cds-question@unistra.frquasarsphotometryWe present the historic light curve of 1WGA J0447.9-0322, spanning the time interval from 1962 to 1991, built using the Asiago archive plates. The source shows small fluctuations of about 0.3mag around B=16 until 1986 and a fast dimming of its average level by about 0.5mag after that date, again with small short-term variations. The variability pattern is within the values shown by other QSOs with long-term monitoring, notwithstanding its high X-ray/optical ratio. We also present its overall spectral energy distribution using literature data and recent UV-optical Swift observations.2007AJ....133..965Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/965CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/965https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/965http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/965https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/965https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/965http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/965GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/133/965/table2The B magnitudes of 1WGA J0447.9-0322recnoRecord number assigned by the VizieR team.
