The authors have looked at a months worth of data from the CANOPUS magnetometer array (Canadian Auroral Network for the OPEN Program Unified Study) in conjunction with satellite observations from GOES 7 taken in March 1990. Applying filtering techniques they extract Pc 5 type event signatures from this data, and find several events clearly observable in both data sets. The satellite indicated dominantly compressional type events associated with field line resonances. The ground system allows the observation of polarization characteristics, in addition to being able to infer points of origin for the wave events. They then correlate the satellite observations versus relative position from the wave origin. This study shows daily variations in the signals and implies an origin for these compressional waves near local noon.
