Three events where coherent oscillations in the solar wind are correlated with Pc5 field line reso-nance oscillations observed by SHARE, the SuperDARN radar at Sanae Antarctica, are analyzed using multitaper methods. The existence of coherent oscillations in the solar wind preceding the ULF pulsations is significant at better than the 95 % confidence level. Estimates of the coherence between oscillations ob-served at WIND and ACE, 200RE apart are significant at the 95 % level or better. There is strong correlation between the Antarctic radar and solar wind observations. We conclude that on occasion coherent oscilla-tions in the solar wind can drive ULF pulsations.
