Summary
In this paper we examine the geomagnetic signatures of solar wind impulses using magnetometer array data, a bistatic HF radar, and a co-located imaging riometer. The impulses were associated with 1.6mHz magnetic pulsations that were observed across a wide range of latitudes. These were most likely due to field line oscillations driven by incoming fast mode waves. At the same time, the radars recorded oscillatory velocity features in ground backscatter returns consistent with ionospheric motions driven by the downgoing waves. Accompanying decreases in cosmic noise absorption were evident in the imaging riometer data.
