The following article gives the results based on observations of EZ Aquilae, extending over 24 years. A mean light curve is derived and an accurate period, also an improved epoch. It is shown that there are minor irregularities in the curve, particularly near secondary minimum. The mean magnitude deviations for points on the curve, two points for each day, are determined. Besides the visual curve, photographic observations in blue light and in red light show curves similar in general shape.
