We present results of two-color photometric study of the newly discovered EW– type eclipsing binary star GSC 04370-00206 in the field of the intermediate polar MU Cam. CCD V,R observations were obtained in the Astronomical Observatories in Hlohovec, Baja and
Kolonica in 2007-2009. Improved photometric elements
for the primary minimum were determined:
Min.BJD=2454805.75635+0.44264511(27)E. The  range of the brightness variations is 13.79-14.13 (V)
and 13.07-13.44 (R). The accuracy of the period
determination is by a factor of ∼ 7, 000 times better
than the one published by the discoverers based on only one night of observations. We report on the night-to-night variability of the shape of the light curve which is interpreted by a presence of spots in  the atmosphere of one or both components (O’Connel effect).
