cds-question@unistra.frvariable-starssolar-system-planetsphotometryWe report a stellar flare occurring during a transit of the exoplanet OGLE-TR-10b, an event not previously reported in the literature. This reduces the observed transit depth, particularly in the u'-band, but flaring could also be significant in other bands and could lead to incorrect planetary parameters. We suggest that OGLE-TR-10a is an active planet-hosting star and has an unusually high X-ray luminosity.2009A&A...505..901Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/505/901CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/458/997 : Abundances for 6 transiting planet host stars (Santos+, 2006)J/ApJ/655/1103 : Five transits of the exoplanet OGLE-TR-10b (Holman+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/505/901https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/505/901http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/505/901https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/505/901https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/505/901http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/505/901GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/505/901/table2VLT-ULTRACAM u'g'i'-band photometry of OGLE-TR-10recnoRecord number assigned by the VizieR team.
