Abstract: The poster deals with the possible variability of GSC 2696-2622. GSC 2696-2622 is located in the vicinity of the eclipsing binary CG Cyg and thus the former has been chosen several times as a comparison star of the latter. Therefore, variability in the brightness of GSC 2696-2622 could lead to incorrect conclusions of the CG Cyg behavior, a fact that renders the clarification of its photometric features highly crucial. Our work focuses on high resolution and precision photometric observations taken by two observatories during July of 2008. The results, supported by Fourier analysis, confirm that the star is a semi-periodic one with variable amplitude that varies on hourly timescales.
