Abstract:

The data were acquired with a heavy-ion sensor aboard the S3-2 satellite in the time period between 24 December 1975 and 3 March 1976. At L 3.25, 0.35 or B 0.25, E 250 KeVnucleon, mirroring fluxes of 370Sq cm- sec-sr He ions and 0.25Sq cm-sec-sr CNO ions were observed. Thus the CNOHe ratio was approx. 6,800,000. Equatorial measurements Spjeldvik and Fritz, 1978c Hovestadt et al., 1978 gave a much larger HeCNO ratio clearly magnetospheric processes strongly discriminate against populating the low-altitude regions with ions of increasing mass in the energy range of hundreds of KeV. In addition, a comparison of the S3-2 data with that from INJUN 5 acquired in January 1969 in the same region of the magnetosphere indicated that the low altitude CNOHe ratio is strongly time dependent.
