Abstract
Fluctuations in the geomagnetic field were measured by three orthogonally mounted coil sensors at two land sites separated by 4 km. Computer generated voltage vs time and magnetic field vs time plots failed to reveal the presence of dominant micropulsations . A coherence study between the two sites revealed coherence values of 0.6 - 0.8 in the frequency range 0.04 - 0.6 Hz. This is compared to a coherence study completed at the Naval Air Development Center, Warminster, Pennsylvania, between land sites 24.8 km apart. The NADC coherence values are lower (0.3 - 0.6).
