cds-question@unistra.frnovaevariable-starscataclysmic-variable-starsphotometryThe 22 yr light curve of HR Lyr, acquired with a typical cadence of 2-6 days, is examined for periodic and quasi-periodic variations. No persistent periodicities are revealed. Rather, the light curve variations often take the form of nearly linear rises and falls having typical e-folding times of about 100 days. Occasional ~0.6mag outbursts are also seen, with properties similar to those of small outbursts found in some nova-like cataclysmic variables. When the photometry is formed into yearly averages, a decline of 0.012+/-0.005mag/yr is apparent, consistent with the fading of irradiation-induced Mdot following the nova. The equivalent width of H{alpha} is tabulated at three epochs over the interval 1986-2008 in order to compare with a recent result for DK Lac in which H{alpha} was found to be fading 50 yr after the nova. However, our results for such a fading in HR Lyr are inconclusive.2014AJ....147..105Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/147/105CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/PASP/125/126 : Light curve of CR Boo over 1990-2012 (Honeycutt+, 2013)J/PASP/109/441 : Northern Cataclysmic Variables (Henden+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/147/105https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/147/105http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/147/105https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/147/105https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/147/105http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/147/105GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap3.322582951404819e-19 3.852589004194616e-19OpticaldefaultJ/AJ/147/105/table1HR Lyr photometry by observing campaignrecnoRecord number assigned by the VizieR team.
