The first multicolor observations , and light curve solutions , of the eclipsing binary systems V1009 Per and CRTS J031642.2+332639 are presented .
Using the 2005 version of the Wilson-Devinney code , both systems are found to be W UMa contact binaries .
V1009 Per has a mass ratio of q = 0.362 \pm 0.002 and a shallow fill out parameter of f = 11.8 \pm 0.6 \% while CRTS J031642.2+332639 has a mass ratio of q = 2.507 \pm 0.006 and a fill out of f = 13.6 \pm 0.4 \% .
High orbital inclinations , i = 85 ^ { \circ } .9 for V1009 Per and i = 83 ^ { \circ } .2 for CRTS J031642.2+332639 , implies that both systems are total eclipsing binaries and that the photometric parameters here obtained are reliable .
Based on 16 times of minimum , the orbital period variations of V1009 Per are discussed .
The absolute dimensions of the systems are estimated and , from the logM-logL diagram , it is found that both components of the systems follow the general pattern of the W subtype W Ursae Majoris systems .
