We present preliminary results obtained from a search of variable stars in the field of the open cluster NGC6250, projected onto the Galactic disk. Our study is based in the analysis of photometric near-infrared data in the J, H and Ks bands obtained with the 4.1m VISTA telescope of the VVV (Vista Variables in the Vía Láctea). With the obtained light curves, and the corresponding periods and amplitudes, we performed a first classification of the new variables detected. We also present the color-magnitude diagram of the open custer NGC 6250.
