Eight variables were found; all but one (a detached eclipsing binary) are small-amplitude ({Delta}V<=0.1mag) pulsating stars of the {delta} Scuti, SX Phoenicis, or Doradus type. The BV color-magnitude diagram extends down to the solar-type stars at V=24 (M_V_~5.2). The cluster age is estimated at 1.5Gyr for Z=0.004 ([Fe/H]=-0.67); the surrounding stellar field is older, with an age greater than 4Gyr.2003AJ....126..237Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/126/237CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/183 : Cluster System of the LMC (Kontizas+ 1990)J/AJ/117/238 : LMC extended catalog (Bica+, 1999)J/A+AS/110/533 : Clusters and field stars in LMC.
