| Summary: | Gross features of the diurnal occurrence pattern for magnetic micropulsations and associated electron precipitation occurring during auroral substorms will be reviewed. Recent observations of 25-250 kev auroral X-rays obtained during August 1967 at Ft- Yukon, Alaska by the Rice University Balloon Group will then be discussed and compared with magnetic micropulsation data recorded during this period at College, Alaska. Particular emphasis will be placed upon the relationship of the energy and frequency spectrum of the precipitated electrons to the occurrence and spectral features of pc 1 band (5~*2 cps) magnetic micropulsations which occur during the afternoon sector (local time interval 1200-1800). A search for possible systematic relationships between the frequency and energy characteristics of the precipitated electrons with corresponding features of the magnetic micropulsations will be carried out. Previous comparisons have proved inconclusive because of limited data on electron precipitation at these local times. |
