 Three new variable stars (HMB11 = USNO-B1.0 1249-0502361, HMB12 = USNO-B1.0 1250-0498893 and HMB13 = USNO-B1.0 1251-0501729) have been identified in the field of the RR Lyrae variable star GY Peg. Full light curves for all the three stars are presented. The form of the light curve indicates that two of the stars (HMB11 and HMB12) are EW type variable stars and the third star (HMB13) is an RRab type RR Lyrae variable star. For HMB11 a period P = 0. 31875 +/- 0.00005 [d] with the epoch E0 = HJD 2454333.747 and an amplitude of the light variation of delta m = 0.20 +/- 0.05 mag. has been found. For HMB12 a period P = 0. 27810 +/- 0.00005 [d] with the epoch E0 = HJD 2454340.720 and an amplitude of the light variation of delta m = 0.15 +/- 0.05 mag. has been found. And finally for HMB13 a period P = 0. 6278 +/- 0.0002 [d] with the epoch E0 = HJD 2454340.774 and an amplitude of the light variation of delta m = 0.75 +/- 0.02 mag. has been found.

Simbad object(s): USNO-B1.0 1251-0501729, USNO-B1.0 1250-0498893, USNO-B1.0 1249-0502361,
