The EUV spectrometer in the AEROS program
Abstract
Solar photon flux at 106 to 16 NM during the declining solar cycle 20 was observed. From these measurements, EUV indices were derived, representing the EUV fluxes in absolute numbers. In addition, atomic oxygen temperatures and densities were derived from attenuation measurements of specific solar emissions, by means of EUV absorption analysis. The combination of these data sets is a powerful tool for observing the upper atmosphere response to variations of the solar EUV flux, e.g., the oxygen density and temperature. The same experiment allowed the study of other subjects, such as the South Atlantic Anomaly, multiplies degradation, satellite mutation, etc.
