Magnetic Field Observations in High β Regions of the Magnetosphere
For a description of the distortions of the geomagnetic field in the magnetosphere ΔB provides a useful measure. Figure 1 shows approximate equi-ΔB contours for the two 90° sectors centered at the noon and midnight meridian half planes, based on a preliminary sampling of a much greater body of OGO 3 and 5 rubidium magnetometer data.
