Partial light curves and updated ephemeris of seven short-period eclipsing binaries: V676 Centauri, HY Pavonis, AA Ceti, BP Velorum, RT Hydri, BF Pavonis and BC Gruis are presented. The photometric UBV observations were obtained with the 76 cm telescope at El Leóncito (Félix Aguilar Station) and with the 2.15 m telescope at CASLEO Observatory. The period of BC Gru was substantially modified. All the observed systems present the typical characteristics of close binaries with different degrees of thermal contact.
