Ground Sites: Mapping of Solar Wind KHI Periodicities and the Subsequent Generation of Compressional/Breathing Pc5 Modes

Herein we present the on the impact of multiple high speed solar streams, stemming from co-rotating interaction regions, on the Earth's magnetospheric system as observed during the summer of 2008. Utilizing ACE, GOES, and ground-based fluxgate magnetometer data, we map ULF activity in the the solar wind to the ground. These ULF signatures are shown to be highly correlated and exhibit coupled spectra structures. The generation of compressional/breathing Pc5 modes in the magnetosphere is discussed.
