Abstract:
In 2008-2013, we obtained 11333 CCD BV Ic frames for 57 Cepheids from
the General Catalogue of Variable Stars. We performed our observations
with the 76-cm telescope of the South AfricanAstronomicalObservatory
(SAAO, South Africa) and the 40-cm telescope of the Cerro Armazones
Astronomical Observatory of the Universidad Catolica del Norte
(OCA, Chile) using the SBIG ST-10XME CCD camera. The tables of
observations, the plots of light curves, and the current light
elements are presented. Comparison of our light curves with those
constructed from photoelectric observations shows that the differences
between their mean magnitudes exceed 0.05mag in 20% of the cases. This
suggests the necessity of performing CCD observations for all
Cepheids.
