THE TEMPORAL VARIATIONS OF ELECTRON INTENSITIES AT LOW ALTITUDES IN THE OUTER RADIATION ZONE AS OBSERVED WITH SATELLITE INJUN 3.
Abstract
Temporal variations of the intensities of electrons (E > 40 keV, > 230 keV, > 1.6 MeV) trapped in the outer radiation zone in the region 3.0 < or L < or 6.0 and mirroring at altitudes of approximately 1500 km have been studied during a seven-month period from January 1 to July 31, 1963, by means of three Geiger-Mueller tubes on-board the U. of Iowa/Office of Naval Research research satellite Injun 3. From observations during some twenty geomagnetically disturbed periods, it is shown that the largest intensity variations occur at the onset of such disturbances and that subsequent behavior is dependent on the magnitudes of the disturbances as measured by the maximum daily sums of the planetary magnetic disturbance parameter, K sub p. The time histories of these intensity variations are compared with those of 3-hour averages of the horizontal component of the geomagnetic field at College, Alaska (L = 5.5), for several disturbed periods.
