Abstract:	Our BVI photometric observations reveal that GSC 2701-2527 is a high amplitude ᵟ Scuti star with quite low temperature. The frequency analysis exhibits that it is multiperiodic pulsator. The obtained period ratio f1/ f2=0.791 is higher than the canonical value. The large value of the period ratio f1/ f3=0.813 implies nonradial nature of the third mode. Using empirical relations for the ᵟ Scuti stars we determined the global parameters of GSC 2701-2527: luminosity 26.2 L⊙, radius 3.95 R⊙, mass 2.18 M⊙, and distance 506 pc.
