Аннотация:The first high accuracy UBVRI(RI)c light curves of poor investigated eclipsing starV1103 Cas = GSC 3682 736 (P=6.18 days, V=11.16 mag., e=0.27, Sp=B3 V) was obtained. The geometric orbit of the system was built, the following physical characteristics of the system were found: T1=16110±400K, M1=5.9±0.3Msun, R1=4.41±0.08Rsun, T2=16010±400K, M2=5.4±0.3Msun, R2=3.77±0.08Rsun. The age of the components is 59 mln years. The photometric parallax pi=0.00052"±0.00002", is close to GAIA DR1 value pi=0.0006"±0.0003". We found fast apsidal motion dw/dt=0.42deg/year which is much bigger than the theoretical value under synchronism condition: dw/dt=0.31deg/year. WDS catalogue is erroneously states that the star is the close optical pair.
