在一系列高频大气实验中探测到了来源不明的电磁波。已经对这些波进行了一年多的方向记录。从这些记录中获得的数据显示，到达方向的水平分量在大约24小时内发生大约360度的变化，这种变化可以用地球的每日自转来解释。此外，这些波达到最大值的时间和它们在那个时间到来的方向在一年中逐渐变化，这种变化可以用地球绕太阳旋转的方式来解释。这些事实导致这样的结论，即这些波的到达方向在空间中是固定的;即，这些波来自太阳系外的某个源头虽然这个源的赤经可以相当精确地从数据中确定，误差不超过± 7.5度，但由于仪器的限制以及地球大气层电离层和波在经过地球表面时衰减可能引起的误差，因此只能近似地确定源的赤经。因此，获得的值可能误差高达± 30度。
Electromagnetic waves of an unknown origin were detected during a series of experiments on atmospherics at high frequencies. Directional records have been taken of these waves for a period of over a year. The data obtained from these records show that the horizontal component of the direction of arrival changes approximately 360 degrees in about 24 hours in a manner that is accounted for by the daily rotation of the earth. Furthermore the time at which these waves are a maximum and the direction from which they come at that time changes gradually throughout the year in a way that is accounted for by the rotation of the earth about the sun. These facts lead to the conclusion that the direction of arrival of these waves is fixed in space; i.e., that the waves come from some source outside the solar system. Although the right ascension of this source can be determined from the data with considerable accuracy, the error not being greater than ±7.5 degrees, 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 source can be determined only approximately. Thus the value obtained might be in error by as much as ±30 degrees.
