Abstract:
In 2008-2010, we obtained 6095 CCD frames in the BVIc photometric
system for 49 classical Cepheids discovered in the ASAS-3 project. The
observations were obtained on the 76-cm telescope of the South African
Astronomical Observatory (SAAO, RSA) and the 40-cm telescope of the
Cerro Armazones Observatory of the Catholic University of the North
(OCA, Chile), with a SBIGCCD ST-10XME camera. We present tabulated
observations, light curves, and revised elements for the brightness
variations.
