Summary
In this study, we present CG Aur's photometric observations obtained in the observing seasons 2011 and 2012, the first available multi-colour light curves. Their shape indicates that the system is an Algol binary. The light curve analyses reveal that CG Aur is a detached binary system with an effective temperature difference between the components, approximately 1000 K. The first estimate of the absolute dimensions of the components indicated that the system locates on the main sequence in the HR diagram. The primary component is slightly evolved from the ZAMS.
