説明
<jats:p>Data from the third rocket of the Substorm‐GEOS series have been studied. The rocket was launched from ESRANGE on January 27, 1979 at 21.52.20 UT into a pulsating aurora.</jats:p><jats:p>Measurements were performed in the energy range 0‐33 keV with electrostatic analyzers and above 48 keV with solid state detectors. The pulsations are visible in the data above 3‐4 keV.</jats:p><jats:p>In a pulsation maximum the bulk of the energy flux is carried by electrons of energies between 5 and 40 keV. In pulsation minima the bulk of the energy flux is carried by particles of lower energies. In the electron fluxes above 25 keV a modulation of about 3 Hz is seen in the loss cone. This modulation is seen only in pulsation maxima and the modulation depth increases with increasing energy.</jats:p>
