✦ Synopsis
Through spectral analysis of GOES magnetometer data, we have found anomalous short-period pulsations occurring prior to solar proton events. The characteristics of these pulsations are: (1)both the H e (Earthward) and H n (eastward) components of the geomagnetic field show the occurrence of pulsations on the same day, and (2)the period of pulsation of H e and H n is greater than 48 s. For large events, this signature may occur up to 2 weeks prior to the solar proton event. It is suggested that this signature may provide a new tool in the forecasting of solar proton events.
