cds-question@unistra.frglobular-star-clustersvariable-starsWe report discovery of 3 new faint variables in the globular cluster NGC 288: 2 SX Phe stars and 1 contact binary. Both SX Phe variables are blue stragglers. The contact binary is located below cluster turnoff, slightly to the red of the main sequence. New photometry of 6 previously known variables is also presented. We note that 26 out of a total 43 SX Phe stars identified recently in {omega} Cen and NGC 288 exhibit V-band light curves with full amplitudes smaller than 0.10mag. The sample of known SX Phe stars is likely to be significantly incomplete in regard to the low amplitude variables.1997A&AS..125..337Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/125/337CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/125/337https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/125/337http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/125/337https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/125/337https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/125/337http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/125/337GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/125/337/table2V-band light curve of variable V2recnoRecord number assigned by the VizieR team.
