Electromagnetic waves of an unknown origin were detected during a series of experiments on atmospherics of short wave-lengths. Directional records have been taken of these waves for a period of nearly two years. The data obtained from these records show that the azimuth of the direction of arrival changes from hour to hour and from day to day in a manner that is exactly similar to the way in which the azimuth of a star changes. This fact leads to the conclusion that the direction of arrival of these waves is fixed in space; that is to say, that the source of these waves is located in some region that is stationary with respect to the stars. Although the right ascension of this region can be determined from the data with considerable accuracy, the error not being greater than +-30 minutes of right ascension, the limitations of the apparatus and the errors that might be caused by the ionized layers of the earth's atmosphere and by attenuation of the waves in passing over the surface of the earth are such that the declination of the region can be determined only very approximately. Thus the value obtained from the data may be in error by as much as +-30 degrees. The data give, for the coordinates of the region from which the waves seem to come, a right ascension of 18 hours and a declination of -20 degrees.
