The Magnetometers Along the Eastern Atlantic Seaboard for Undergraduate Research and Education (MEASURE) array were deployed in 1998 and it runs from low to mid-latitudes (1.74 < L < 3.12) along the east coast of the United State.  In this study, the resonant eigenfrequency and frequency of the peak power in the inner magnetosphere of the earth were determined using this dataset.  The 3 months of January, August, and September of the years 2000 were analyzed for a correlation investigation between the magnetic field resonant eigenfrequency and various magnetospheric pulsations. Furthermore, quantified values of narrowband and broadband power were evaluated and their relations to the eigenfrequency were investigated.
