Through time-series CCD photometry using a 130mm refractor of Busan Science Academy, we found a new δ Scuti type variable star, esc 03665-00576. We performed following observations using a 1.8m telescope of Bohyunsan Optical Astronomy Observatory. Three frequencies have been derived by multiple-frequency analysis, which are 10.968, 7.156 and 15.182cycle day−1, respectively. V-amplitude of esc 03665-00576 is ΔV= 0.04.

Through time-series CCD photometry using a 155mm refractor, we found a new δ Scuti type variable star, HD 235428, near a known bright δ Scuti type star, DQ Cep. We performed follow-up observations using a 61cm telescope at Sobaeksan Optical Astronomy Observatory. Four frequencies have been derived by multiple-frequency analysis, which are 15.804, 5.498, 15.351 and 24.516cycle day−1 , respectively. V-amplitude of HD 235428 is ΔV = 0.026.
