These times, together with 20 times of maximum taken from the literature, lead to a new local linear ephemeris for 2003-2009 with a formally slightly shorter period than the one for 1996-2002. It will require at least another half decade of additional monitoring before any significant update to any model can be considered. Such monitoring should preferably occur at regular intervals, be done in a consistent photometric band, and at high time resolution. A set of 114 new times of maximum obtained since 2002 leads to a new local linear ephemeris for 2003-2009: Tmax=2426159.512(+/-0.001)+0.061038349E(+/-0.000000002).2010JAD....16....2Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/JAD/16.2CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/JAD/16.2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/JAD/16.2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/JAD/16.2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/JAD/16.2https://vizier.iucaa.in/viz-bin/votable?-source=J/other/JAD/16.2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/JAD/16.2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/other/JAD/16.2/table3Times of maximum light of CY AqrrecnoRecord number assigned by the VizieR team.
