The δ Scuti star GP Andromedae was observed at Cluj‐Napoca Astronomical Observatory between 2002 and 2008. During this period we obtained more than 10,000 CCD frames in 20 nights, containing five possible comparison stars. The differential photometry of these stars revealed possible long term varibility for one of them, while preliminary statistical analyses emphasizes the possible microvariability in at least two other cases. The variability survey of these stars is approached through complementary methods. The preliminary results of our analyses are presented.
