cds-question@unistra.frstellar-flaresmultiple-starsThe results of U-filter flare monitoring of the binary flare star FL Vir = Wolf 424 is presented. 57 flares with energies between 2x10^28^ and 2x10^31^erg were recorded in 20h of observation. The properties of flare occurrence and flare time-scales are analysed, and the flare activity level in 1980 April is determined to be L_f_(U)=8.0x10^26^erg/s. This is larger than previously published results and may indicate a variation in the flare activity level on a time-scale of years. An analysis of existing data indicates that the flare activity level correlates with the relative orbital positions of the stars.2006MNRAS.368.1392Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/368/1392CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/368/1392https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/368/1392http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/368/1392https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/368/1392https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/368/1392http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/368/1392GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/368/1392/table2U-filter flare characteristics for FL VirrecnoRecord number assigned by the VizieR team.
