Zusammenfassung:	Observations of the eclipsing binary 44i Boo were obtained in 1978 at the Biruni Observatory in Iran. Topics discussed include the properties of the photoelectric light curve of 44i Boo, the observational technique employed, the phase determination of the time of observations, and the reduction of the data points. The midpoint of each fluctuation and its deflection are determined for each filter, and two methods for reducing the charts are proposed. The final light curves of 44i Boo in u,v,b, and y are analyzed. (R.R.)
