Photometric observations and analysis of FY Lac were performed in order to determine the variability characteristics, using measurements taken at Loiano site of Bologna Astronomical Observatory and AAVSO data. The star shows a Long Term variability with a preliminary period of about 274 +/- 28 days and photometric characteristics compatible with a red M5 III giant star, with a temperature of 3420 K degrees.
