Abstract

The X-ray spectrum of the quiet Sun in the energy range 2.3–6.9 keV was observed from an Aerobee rocket using an uncollimated graphite crystal spectrometer. These results and spatial measurements made with an onboard modulation collimator are analyzed using solar models. Several methods of estimating coronal temperatures are used in the analysis and all yield results within the range (4±l) × l06K.
