LIGHT VARIATIONS OF THE SPECTRUM VARIABLE HD 4778 = HR 234

HD 4778 shows light variations with a period of 2ḍ156. The light curve obtained with the V filter is phase shifted by nearly 180 degrees with respect to the light curve in blue and ultraviolet. The maximum light in U and B corresponds to the maximum of the intensity of the Ca ii K line.
