Using CCD observations photometric magnitudes have been obtained in 18 sub-fields in a direction at intermediate galactic lattitude (l = 170°, b = 45°) in the 14 deg2 area. B and V magnitudes have been obtained for a total of 214 stars out of which for 73 stars U magnitudes also have been obtained. The magnitude range covered is 11 < V < 21 and 0.18 < B-V < 1.85
